(15) You shall make a breastpiece of decision, worked into a design; make it in the style of the ephod: make it of gold, of blue, purple, and crimson yarns, and of fine twisted linen. (16) It shall be square and doubled, a span in length and a span in width.


(17) Set in it mounted stones, in four rows of stones. The first row shall be a row of carnelian, chrysolite, and emerald; (18) the second row: a turquoise, a sapphire, and an amethyst; (19) the third row: a jacinth, an agate, and a crystal; (20) and the fourth row: a beryl, a lapis lazuli, and a jasper. They shall be framed with gold in their mountings. (21) The stones shall correspond [in number] to the names of the sons of Israel: twelve, corresponding to their names. They shall be engraved like seals, each with its name, for the twelve tribes.


(22) On the breastpiece make braided chains of corded work in pure gold. (23) Make two rings of gold on the breastpiece, and fasten the two rings at the two ends of the breastpiece, (24) attaching the two golden cords to the two rings at the ends of the breastpiece. (25) Then fasten the two ends of the cords to the two frames, which you shall attach to the shoulder-pieces of the ephod, at the front. (26) Make two rings of gold and attach them to the two ends of the breastpiece, at its inner edge, which faces the ephod. (27) And make two other rings of gold and fasten them on the front of the ephod, low on the two shoulder-pieces, close to its seam above the decorated band. (28) The breastpiece shall be held in place by a cord of blue from its rings to the rings of the ephod, so that the breastpiece rests on the decorated band and does not come loose from the ephod.


(29) Aaron shall carry the names of the sons of Israel on the breastpiece of decision over his heart, when he enters the sanctuary, for remembrance before the LORD at all times.


(30) Inside the breastpiece of decision you shall place the Urim and Thummim, so that they are over Aaron’s heart when he comes before the LORD. Thus Aaron shall carry the instrument of decision for the Israelites over his heart before the LORD at all times.

Here in this passage of Parashat Tetzaveh, God describes to us how to make a holy breastplate named the Choshen. The instructions are detailed, explaining what stones to use, what threads to use, and when it is supposed to be worn. What is interesting is that it isn't described why the stones are necessary and how we are supposed to use the choshen to communicate to god.

Questions I have:

  1. What are Urim and Thummim?
  2. How do the stones correlate to one another?
  3. What is the correlation between the stone and their inscribed tribe?
  4. Why is it called the breastplate of decision/judgement or "חֹ֤שֶׁן מִשְׁפָּט֙"?
  5. When did Jews stop using the Choshen? Why?
  6. Where is the oldest excavated Choshen?
  7. Could we create a choshen (exactly how it is instructed to be made) and use it today?
  8. Are there any midrashim on the Choshen?

Question #1 - What are Urim and Thummim?

(א) את האורים ואת התמים. הוּא כְּתָב שֵׁם הַמְפֹרָשׁ, שֶׁהָיָה נוֹתְנוֹ בְּתוֹךְ כִּפְלֵי הַחֹשֶׁן, שֶׁעַל יָדוֹ הוּא מֵאִיר דְּבָרָיו וּמְתַמֵּם אֶת דְּבָרָיו; וּבְמִקְדָּשׁ שֵׁנִי הָיָה הַחֹשֶׁן – שֶׁאִי אֶפְשָׁר לְכֹהֵן גָּדוֹל לִהְיוֹת מְחֻסַּר בְּגָדִים – אֲבָל אוֹתוֹ הַשֵּׁם לֹא הָיָה בְּתוֹכוֹ, וְעַל שֵׁם אוֹתוֹ הַכְּתָב הוּא קָרוּי מִשְׁפָּט, שֶׁנֶּאֱמַר (במדבר כ"ז), וְשָׁאַל לוֹ בְּמִשְׁפַּט הָאוּרִים (יומא ע"ג):

(1) את האורים ואת התמים THE URIM AND THE THUMMIM — This was an inscription of the Proper Name of God which was placed between the folds (i. e. the two pieces forming the front and back) of the breast-plate through which it (the breast-plate) made its statements clear (lit., illuminated its words; מאיר from אור, light, this being an allusion to the אורים) and its promises true (מתמם from the root תמם, an allusion to תמים) (Yoma 73b). In the second Temple there was certainly the breast-plate (although other objects employed in the Temple Service were missing) for it was impossible that the High Priest should have lacked a garment, but that Divine Name was not within it. It was on account of the inscription which constituted the Urim and Thummim and which enabled it to give decisions that it was called “judgment”, as it is said, (Numbers 27:21) “And he shall enquire for him by the judgment of the Urim” (Numbers 27:21).

Rabbi Shlomo Yitzchaki, or "Rashi" lived in Troyes, France from 1040 - 1105 C.E. "In his commentary, [Rashi] states that his purpose is to present the pshat (contextual meaning) of the text."

Rashi illuminates our understanding of Urim and Thummim by providing us with the knowledge that together Urim and Thummim are able to make statements clear, and they possess good judgement.

תנו רבנן כיצד שואלין השואל פניו כלפי נשאל והנשאל פניו כלפי שכינה השואל אומר (שמואל א ל, ח) ארדוף אחרי הגדוד הזה והנשאל אומר כה אמר ה' עלה והצלח רבי יהודה אומר אין צריך לומר כה אמר ה' אלא עלה והצלח אין שואלין בקול שנאמר (במדבר כז, כא) ושאל לו ולא מהרהר בלבו שנאמר ושאל לו לפני ה' אלא כדרך שאמרה חנה בתפלתה שנאמר (שמואל א א, יג) וחנה היא מדברת על לבה
§ The Sages taught: How does one consult the Urim VeTummim? The one asking stands with his face toward the one who is asked, i.e., the High Priest or the priest anointed for war. And the one who is asked, the High Priest, turns his face toward the Divine Presence, i.e., the Urim VeTummim, in which the explicit name of God is found, by tilting his head downward toward it. The one who asks says his question, e.g.: “Shall I pursue after this troop?” (I Samuel 30:8). And the one who is asked answers him according to the response he receives and says, for example: Thus says God: Go up and succeed. Rabbi Yehuda says: He need not say the words: Thus says God; rather, it is sufficient to relay the content of the response and say: Go up and succeed, since he is obviously only repeating what he was told. One does not ask in a loud voice, as it is stated: “And he shall stand before Elazar the priest, who shall inquire for him by the judgment of the Urim” (Numbers 27:21), which implies that the inquiry is to be audible only to the person asking. And he should not think his question in his heart but should enunciate it, as it is stated: “And…who shall inquire for him by the judgment of the Urim before God” (Numbers 27:21), and immediately afterward it states: “By his mouth” (Numbers 27:21). Rather, how shall he inquire? He should do so akin to the way that Hannah spoke in her prayer, as it is stated: “Now Hannah spoke in her heart; only her lips moved, but her voice could not be heard” (I Samuel 1:13), which indicates she did enunciate the words but spoke so quietly that no one else could hear.

Composed in Talmudic Babylon (c.450 - c.550 CE). Yoma means "the day" it discusses the prescriptions Yom Kippur, especially the ceremony by the Kohen Gadol.

In Yoma 73a it is described that if one shall approach Urim and Thummim, they shall enunciate the words of their request but speak so quietly that no one else can hear". An example of a question asked would be "should I advance after this troop?" Therefore the powers of the stones are revealed in that they are prophetic.

Therefore I believe that Urim and Thummim were stones best used in unison. The Urim would fully understand the situation brought up by the individual, while the Thummim (which possessed good judgement) would be able to assess the situation and see whether or not it would be a good idea to bestow prophetic knowledge upon the individual. I also think that their prophetic powers originate from the fact that the "inscription of the Proper Name of God ... was placed between the folds" (Rashi Exodus 28:30:1).

Video upon Urim and Thummim, delves into the roots of both words. ״ארר״ or "arar" is the root of ״אורים״ (Urim) meaning curse. While ״תמם״ or "tamam" is the root of ״תומים״ (Thummim) meaning complete. Together they equate a type of "true or false". The video also describes how the letters upon the Choshen would light up to write a word which would be the answer to an individual's question.

Question #2: How do the stones correlate to one another?

(א) איש על שמו. כְּסֵדֶר תּוֹלְדוֹתָם סֵדֶר הָאֲבָנִים, אֹדֶם לִרְאוּבֵן, פִּטְדָה לְשִׁמְעוֹן, וְכֵן כֻּלָּם:

(1) איש על שמו EVERY ONE WITH HIS NAME — As the order in which they were born shall be the order of the stones: a sardius for Reuben, a topaz for Simeon, and so in the case of all of them.

Rashi believed that each stone correlates to one another in their order. The order in his opinion was the age of the tribes name.

(א) אדם שרדנא, ומצאתי בהגהה אלמנדיגא. (ב) פטדה אמירלא. (ג) ברקת אטופצרי. (א) נפך קרבונקלא. (ב) ספיר שפיר. (ג) יהלם בריקלא. (א) לשם אלמנדסה. (ב) שבו אמטיטה. (ג) אחלמה גירגונסא. (א) תרשיש קרישטלי נמצא בהגהה פרזמא. (ב) שהם אוניקלא. (ג) ישפה ישפי. (א) איש על שמו פרש״‎י כסדר תולדותם סדר האבנים אודם לראובן פטדה לשמעון וכן כולם. חז״‎ק לפרש״‎י דאם כן לא יגיע לשם לדן ובס׳‎ שופטים כתיב ויקראו ללשם דן בשם אביהם. ושם פרש״‎י ששמו של דן כתוב על לשם. לפיכך יש מפרשים כסדר תולדותם היינו כסדר לידת האמהות לאה בלהה זלפה רחל ועכשיו יגיע לשם לדן.

(1) אדם, a “carnelian;” (2) פתדה, a “chrysolite;” (3) ברקת “emerald;” (1) נפך, “a turquoise;” (2) ספיר, “a sapphire;” (3) יהלם, an “amethyst" (1) לשם, “a jacinth;” (2) שבו, "an agate;" (3) אחלמה, “a crystal;” (1) תרשיש, "a beryl"; (2) שהם, "a lapis lazuli"; (3) ישפה, "jasper." (1) איש על שמו, each jewel symbolised the name of the tribe in whose row it was placed and engraved.. According to Rashi, the order in which these jewels have been named here corresponded to the order in which the names of the twelve tribes had been arranged on the breastplate, in order of their ages. If Rashi were correct, then the jewel leshem should not have been the one symbolising the tribe of Dan, as is clear from Joshua 19,47. We would have to say therefore that the order followed the ages of their respective mothers, i.e. Leah, Bilhah, Zilpah, Rachel. When we accept this then the jewel leshem corresponds to the position of Dan on the breastplate.

Rashi's statement is debunked by Chizkuni who also translates the stones into what Sefaria uses today in its main translation of the text. Chizkuni also discovered that the order of the stones followed the ages of their mothers. To me, this seems a little farfetched, but maybe it's correct.

Other than that, there seems to be no other correlation between the stones. They do not share powers like Urim and Thummim, nor do they all work in unison. They are independent in their job.

Question #3: What is the correlation between the stone and their inscribed tribe?

The following text is highlighted at your advantage.

ארכו של חושן שתי זרתות ורחבו זרת וכופלו לשנים נמצא זרת על זרת מרובע וקבועים בו ארבעה טורים אבן וכל אבן ואבן היה מרובע, ומפתח שמות י"ב שבטים על י"ב אבנים, ראובן היה מפותח על אבן אודם, שמעון על פטדה, וכן כולם. ומלבד י"ב שבטים שהיו כתובים על י"ב אבנים הללו היו כתובים שמות האבות אברהם יצחק יעקב ושבטי ישרון. וכסדר הזה היו כתובים ראובן א' על אודם, שמעון ב' על פטדה, לוי רה"ם על ברקת, יהודה י' על נופך, יששכר צ' על ספיר, זבולן ח' על יהלום, דן ק' יע"ק על לשם, נפתלי ב' על שבו, גד שבט"י על אחלמה, אשר יש"ר על תרשיש, יוסף ו"ן על שהם, בנימין על ישפה, הרי לך בכל אבן ואבן ששה אותיות להורות כי ששת ימי המעשה תלוים בי"ב שבטים, והיו באבני חושן ע"ב אותיות כי י"ב פעמים ששה הם ע"ב והם כנגד ע"ב אותיות של השם הגדול להורות בזה קיום העולם שנברא בע"ב שעות שהרי העולם נברא ביום שנאמר (בראשית ב ד) ביום עשות ה' אלהים ארץ ושמים, וששת ימי המעשה ע"ב שעות יש בהם י"ב שעות בכל יום, וזהו שאמר הכתוב (תהילים פ״ט:ג׳) אמרתי עולם חסד יבנה כמנין חס"ד, ולמדנו מזה שהעולם שנברא בע"ב שעות מתקיים בזכות השבטים שבהם ע"ב אותיות. (ב) והנה בנימין שהיה מפותח על ישפה היה מלא ולא היה בו סמך אותיות מן האבות כשאר השבטים כי לא נשתיירו מבני בנימין במעשה פלגש בגבעה כי אם שש מאות בזכות בנימין שהיה מפותח באבני החשן ששה אותיות. (ג) ודע כי נמצא כתוב בספרי חכמת הטבע כי כל האבנים היקרות שהם עקריות ושרשיות אינן אלא י"ב והם אבות לכל שאר האבנים וכל השאר מיניהם ענפיהן ותולדותיהן.
ומה שנתן אבן אודם לראובן על שם שהאדימו פניו בחטא בלהה כשבלבל יצועי אביו והודה ולא בוש, והאבן הזאת נקרא רובי"ן והוא גדל במקומות ידועים בים והוא סלע גדול ומוצאו כמוצא הכסף וכמוצא הזהב, והסלע והמוצא ההוא קורין אותו בלאש"ו, ורובינו ובלאש"ו הכל מין אחד וחתיכה אחת, אלא שהרובי"ן הוא אדום בתכלית וכן תרגומו סמקן והוא מבחר האבן כמין ענפים שבולטים ממנו ונמשכים ממנו והבלאש"ו הוא למטה ממנו מאד במעלת האדמימות, ומפני זה נקרא מבחר האבן הזאת בלשוננו אודם כי מראהו אדום כדם וסגולתו שכל אשה שנושאתו אינה מפלת לעולם נפלים ואמרו שהוא טוב לאשה המקשה לילד, ואם היו שוחקים אותו ומערבים אותו באכילה ובשתיה מועיל הרבה להריון כדודאים שמצא ראובן ששם דמות אדם ועל כן נכתב אדם חסר וי"ו להורות על אדם כי המקרא יורה עצמותו של אבן והמכתב בחסרון וי"ו יורה על פעולתו, ומפני זה היה ראובן מפותח על אבן אודם.
שמעון היה מפותח על פטדה היא אבן ירוקה ככרתי בכרכי הים, וכן תרגומו ירקן ונקרא פראשמ"א והוא מין נפך שהוא מרקד"י שהוא ג"כ ירוק ככרתי. ודע כי פראשמ"א ומרקד"י הכל מין אחד וחתיכה אחת כענין שבארתי לך ברובי"ן ובלאש"ו, אלא שהמרקד"י הוא המובחר והוא המלוקט ומחותך ממנו והוא בתכלית הירקות וזיוו מבהיק ואורו מתנוצץ עד מאד והפראשמ"א ירוקה גם כן אבל היא למטה ממנו עד מאד בין בירקות בין בזיו האור, ומה שנתנה האבן הזאת לשמעון על שם שהוריקו פניו של זמרי בן סלוא נשיא שבט שמעון וכן כל מי שחטאו משבט שמעון בבנות מואב הוריקו פניהם, וכן דרשו רז"ל סימן לעברה הדרוקן. וסגולת האבן הזאת של פטדה שהיא מקררת את הגוף וע"כ היא מצויה בארצות כוש שהם חמים ושטופי זמה וצריכים אליה לקרר אותם וזהו שכתוב (איוב כ״ח:י״ט) לא יערכנה פטדת כוש, יחס אותה לכוש שהיא מצויה בארץ כוש.
לוי היה מפותח על ברקת והוא הקרבונקל"א נקראת ברקת על שם שנוצצת כברק ומאירה כנר וכן תרגום ברקן, והוא אבן שתלה נח בתיבה ממה שכתוב (בראשית ו׳:ט״ז) צהר תעשה לתיבה והנביא קראה אקדח שנאמר (ישעיהו נ״ד:י״ב) ושעריך לאבני אקדח על שם שקודח כגחלת והוא מלשון (שם נ) קודחי אש, ונתנה ללוי מפני ששבט לוי היו מאירין בתורה כענין שנאמר (דברים ל״ג:י׳) יורו משפטיך ליעקב ותורתך לישראל, וכן משה שהיה משבט לוי כשנולד נתמלא כל הבית אורה ונאמר בו כי קרן עור פניו וכתיב (קהלת ח׳:א׳) חכמת אדם תאיר פניו, וסגולת האבן הזאת שהיא מחכימת פתי ומאירת העינים מלבד שמשתמשין בעצם גופה כמו שמשתמשין באור הנר ואומרים כי אם שוחקין אותה ומערבים במאכל ובמשתה או בשאר הסמים יועיל הרבה מאד להחכים ולפתוח הלב.
יהודה היה מפותח על נפך והוא מראקד"י ובלשון ערבי זמור"א והתרגום כולל ב' לשונות הללו וע"כ אמר אזמרגדין מורכב מלשון זמור"א ומלשון מראקד"י והאבן ירוקה ככרתי והוא ממין פראשמ"א כמו שהזכרתי ונתנה ליהודה על שם שהוריקו פניו במעשה תמר ונתגבר על יצרו והודה ולא בוש והוריקו פניו גם כן על שחשדו אביו על יוסף הוא שכתוב (בראשית ל׳:ח׳״ז:כ׳) חיה רעה אכלתהו, וכשבא לברך את בניו אמר לו (שם מט) מטרף בני עלית אז נעשו פניו זכים ומבוהקים כנפך הזה שזיוו מבהיק וכן כתוב ביהודה (שם) ידך בערף אויביך וסגולת האבן הזאת שכל מי שנושאם אויביו הופכין לו עורף ולכך נקרא נפך, וכן כתוב ביהודה ידך בעורף אויביך, וכן מצינו תגבורת מלחמת ונצחון בכל שבט יהודה, בדוד כתיב (שמואל א י״ח:ז׳) ודוד ברבבותיו, ובמשיח כתיב (ישעיהו י״א:ד׳) וברוח שפתיו ימות רשע.
יששכר על ספיר והוא הנקרא שפיל"י והוא מראה תכלת, ונתנה ליששכר לפי שהיו גדולים בחכמת התורה שנאמר (דברי הימים א י״ב:ל״ג) ומבני יששכר יודעי בינה לעתים וגו', ולוחות התורה של סנפירינון היו, וכן מצינו במתן תורה (שמות כ״ד:י׳) ותחת רגליו כמעשה לבנת הספיר. וידוע כי נפש בעלי התורה צרורה בצרור החיים תחת כסא הכבוד שכתוב בו (יחזקאל א׳:כ״ו) כמראה אבן ספיר דמות כסא, וצבע זה של תכלת אינו צבע של גאוה כצבע של אדמימות או צבע ירקות שקורין גרי"ן ששניהם צבעים של גאוה, אבל התכלת צבע של ענוה ושפלות נאה לבחורים ונאה לזקנים, וזהו שכתוב (ישעיהו נ״ז:ט״ו) מרום וקדוש אשכון ואת דכא ושפל רוח. וסגולת אבן זה שהוא טוב לאור העינים ולכך מעבירין אותו על העינים, וכן התורה מאירת עינים ואמרו האבן הזאת תועיל לכל כאב ונפיחה באיזה מקום שתהיה בגוף וכן התורה מרפאה לכל הגוף, וכן אמרו רז"ל חש בראשו יעסוק בתורה.
זבולן על יהלום והוא הנקרא פירל"א והיא לבנה כלה על שם שהכסף לבן והוא סימן לעשרו של זבולן שנאמר (בראשית מ״ט:י״ג) זבולן לחוף ימים ישכון לכך נתנה לזבולן והיא מצלחת בפרקמטיא, וסגולת האבן שמביאה שינה על האדם שכן אמר הכתוב (שם ל) הפעם יזבלני אישי.
דן על לשם והוא הנקרא אשטפסי"ס ונמצא בו פרצוף אדם מהופך על שם שהפכו שבט דן את הקערה על פיה והפכו לשם לסמל בפסל מיכה וכתיב בספר יהושע בענין חלוק הארץ (יהושע י״ט:מ״ז) ויקראו ללשם דן כשם דן אביהם כי היא שם עיר מארץ ישראל.
נפתלי על שבו והיא נקראת טורקיז"א והפרשים מתמידים לנושאה וכן תרגומו טרקיא, וסגולת האבן הזאת שהיא מושכת האדם על הרכב ומצלחת אותו בענין הרכיבה כל ימיו ולכך נקראת שבו ועל שהיא מחברת אותו אל הרכב נתנה לנפתלי שהיא לשון חבור על שם (בראשית ל) נפתולי אלהים נפתלתי.
גד על אחלמה והוא הנקרא קרישטא"ל ולכך תרגומו עין עגלא והאבן הנקרא ליאמ"ן דומה לה אלא שיש בה אדמימות, ונתנה אחלמה לגד שכשם שאחלמה והוא קרישטא"ל מצוי הרבה אצל בני אדם והכל מכירים אותו, כך שבטו של גד היו מרובין והרוגיהם נכרין הוא שכתוב (שם לג) וטרף זרוע אף קדקד, וסגולת האבן הזאת שמחזקת את הלב שלא ירך בלכתו למלחמה ולכך נקראת אחלמה מלשון חוזק וכענין שנאמר (ישעיהו ל״ח:ט״ז) ותחלימני והחייני, וכתיב (איוב ל״ט:ד׳) יחלמו בניהם ירבו בבר.
אשר על תרשיש והיא הנקראת קריאוליק"א וגוון שלה דומה לגוון השמן, ויש שפירשו שהיא האבן שצבעה תכלת ותרגומו כרום ימא שהרי גוון הים כעין תכלת, ומצינו ים ששמו תרשיש שנאמר (יונה א׳:ג׳) וימצא אניה באה תרשיש, וסגולת האבן הזאת לעכל המאכל, וכל שכן למי ששוחק אותה ומערבה במאכלו ונעשה בזה עב ושמן והוא שכתוב (בראשית מ״ט:כ׳) מאשר שמנה לחמו.
יוסף על שהם והוא נקרא אוניקל"י, וסגולת אבן זה לתת חן לאדם בעיני כל רואיו ונקראת שהם, ויש בה אותיות השם, על שם (שם לט) ויהי ה' את יוסף ויהי איש מצליח,וכתיב (שם) ויתן חנו בעיני שר בית הסהר ומי שנושאה בבית המלכות תועיל הרבה ויצליח ויהיו דבריו נשמעים.
בנימין על ישפה והיא הנקראת ישפי"ז והיא כלולה מגוונים הרבה אדומה שחורה ירוקה וסגולת האבן הזאת לעצור הדם ונתנה לבנימן לפי שנשתנה לבו לגוונים הרבה וחשב מחשבות במכירתו של יוסף אם יגלה הדבר לאביו אם לא ואעפ"כ נתגבר על יצרו והיה מעצור לרוחו ולא גלה הדבר לאביו, ולכך נתנה לו האבן הזאת, ונקראת ישפה שתי מלות יש פה, וזה יורה על מעלתו שאע"פ שהיה לו פה והיה לו לגלות הדבר שתק ולא גלה. אלה י"ב אבנים הקבועים בבגד החושן ואלה שמותם ושמות י"ב השבטים מפותחים בהם כסדר לידתן שבט ושבט כתוב על אבנו המיוחדת לו והכל בהשגחה גמורה וכוונה נפלאה.
(ד) וראיתי בספר האבנים שחברו הפילוסוף שהאבנים צריכות טהרה וידוע מסגולתם שהנושא אותם בטומאה יתבטל כחם אליו או יחלש ואם ישוב ויטהר תחזור האבן לכחה הראשון כבתחלה, והסבה והטעם בזה לפי מעלות רוחניות הכח העליון שהאבן מושכת ממנו שהוא מדבק בטהרה ומתרחק מן הטומאה, וכן כתב החבר בחבורו, וראוי להאמין כך שהרי אין לך כל אבן ואבן מן האבנים היקרות שלא תמשך כח עליונים כענין שאמר בעשבים אין לך כל עשב ועשב מלמטה שאין לו מזל למעלה. ונמצאת למד שהכהן הגדול בבגדי האפוד והחשן היה מוקף מלפניו ומאחריו משמות י"ב שבטים, החשן אשר על לבו מלפניו היו קבועים שמות י"ב השבטים על י"ב אבניו כל שבט ושבט על אבנו גם האפוד שהיה מאחוריו על שתי כתפיו ששם שתי אבני שהם שהם קבועים בהם מפותחים י"ב שבטים ששה על אבן זו וששה על אבן זו והכהן כאשר ילבשם היה לובשם ביחד האפוד עם החשן שהרי מחובר היה זה בזה שנאמר (שמות כ״ח:כ״ח) ולא יזח החשן מעל האפוד והיה החשן על לבו מלפניו והאפוד מאחריו, וחשב האפוד היה קשור על לבו תחת החשן ושתי כתפות האפוד על ב' כתפיו ושתי עבותות הזהב יורדות מעל כתפות מכאן ומכאן ונתונות תוך טבעות החושן העליונות, ושני חוטין של תכלת מרוכסין מתחת אצילי ידיו מב' טבעות בכתפות האפוד התחתונות שהן למעלה מן החשב.

There were four rows of three gemstones on it, each gemstone being square. The names of the tribes were “inscribed chemically” each tribe’s name in accordance with the colour gemstone reflecting its individuality. Reuven’s name was inscribed on the stone called אודם, Shimon’s on a stone called פטדה, etc., etc. In addition to the names of the twelve tribes the names of the patriarchs Avraham, Yitzchak, and Yaakov were also inscribed plus the words שבטי ישורון. These additional words were distributed between the various stones so that, for instance, the stone אודם with the name Reuven had an additional letter א as part of the name אברהם, whereas the stone פטדה which had the name שמעון inscribed on it also had a letter ב added as the second letter in the name אברהם, and so on. A stone with a short name such as גד, for instance, had the word שבטי of שבטי ישורון added seeing that there was enough space for this. The stone with the name אשר had in addition the letters ישר of the word ישורון inscribed on it, whereas the stone with the name יוסף had the last three letters of the word ישורון inscribed on it also, so that each stone had a total of six letters making an overall total of 72 letters. These 72 letters corresponded to the great name of the tetragram when it is spelled in all its 24 permutations. The six days of creation comprised a total of 72 hours of daylight, the number of hours during which the universe and all that is in was created (no creation took place at night.). We know this as the Torah speaks of ביום עשות ה' אלו-הים ארץ ושמים (Genesis 2,4), “on the ‘day’ Lord G’d made earth and heaven.” This number 72 has also been alluded to in Psalms 89,3 where David speaks about the world having been built on the attribute חסד, loving kindness. The numerical value of the word חסד is also 72. We infer from these verses that the world which has been created in 72 hours of creative activity by G’d is maintained due to the merit of the twelve tribes of Israel, i.e. the 72 letters inscribed in the breastplate of the high Priest. (2) It is remarkable that the stone with the name בנימין which was spelled plene, i.e. with two letters י (as opposed to Exodus 1,3 or Genesis 42,38 et al) where there is no letter י before the final letter ן filled out its stone seeing his name had six letters. It was therefore impossible to add a letter from the patriarchs’ names on his stone. The reason that this was so may be connected to a historical occurrence in the time of the Judges when the tribe came close to extinction, only 600 young men surviving after the civil war described in Judges 20-21. Had his name not been spelled with six letters on the breastplate, even the six hundred young men who survived might not have done so. (3) Scientific books claim that the basic number of gemstones, (not allowing for variants, mutations) are only 12 in number, so that they were all represented on the breastplate of the High Priest. They may be considered as the “patriarchs” of all other precious stones. The reason that the gemstone assigned to the tribe of Reuven was the אודם was the fact that it symbolised the blush on his face when he owned up to being guilty of his misdemeanour in Bilhah’s tent. The fact that he was not ashamed to admit his guilt is a credit to him reflected by this red-coloured stone known as “rubin.” It is supposedly found in certain areas at the bottom of the sea. It is chipped of a great rock beneath the sea, and is mined similar to silver and gold. The rock is known as Balax. Rubin and Balax are supposedly two names for the same kind of stone. The difference between them is only that the variety known as rubin is reddish looking. Onkelos also translates the word אודם as סמקן, a red stone. It is the choicest of a number of sub-categories of the same basic kind of precious stone. Seeing it is red, an essential colour reminding us of blood, it is reputed to have the power to protect a woman who wears this jewel against ever aborting any fetus she carries. Women who wear jewelry made from this stone will give birth to babies that have been growing in their wombs for the full nine months. The stone is even supposed to have positive effects upon women who are having a difficult delivery. If this stone will be crushed into powder and consumed with food and drink it displays properties similar to those of the דודאים (mandrakes?), the plant which Leah “sold” Rachel in order to help her achieve pregnancy (compare author’s comment on Genesis 30,14). The shape of those dudaim which Reuven had found at the time was the outline of a human being. This is the reason that the word אודם, normally spelled with the letter ו was spelled without that letter in order to draw our attention to the spelling which could be read “Adam,”אדם . The reading of the word teaches the nature of the stone, whereas the spelling teaches the effect of that stone, its function.
Shimon’s stone פטדה, is a greenish-looking gemstone, similar to the turquoise colour of the sea in certain coastal cities. Onkelos also translates it as ירקן (emerald?). It is of the same group as the gemstone נפך, the stone with the name of Yehudah inscribed on it. Both are of similar colour, except that the stone described as נפך is the more precious of its group. It sparkles very much. The פטדה is inferior to the נפך both in colour and in sparkle. The greenish colour symbolises the terrible sexual licentiousness committed by that tribe who had caused the face of their leader Zimri to turn green in shame (Numbers 28,14). The same happened to all the other members of the tribe of Shimon who took part in that sin at that time. Darkon, dropsy, was the illness from which these people died. The positive feature of that gemstone is that it cools the body. This may be the reason it is found in hot countries such as Nubia (the Sudan). The people in that country are especially steeped in sexual licentiousness. They need to “cool off” in order to counteract their tendencies. This is why we read in Job 28,19 “topaz from Nubia cannot match its value (that of rubies).” The reason Job made this comparison was because these stones were found in Nubia.
The stone which bore the name of Levi was the ברקת, known popularly as carbuncle (a rounded gemstone without facets). It is so called as it flashes just like a bolt of lightning, ברק. It illuminates like a lamp. Onkelos also translates it as ברקן, a flashing stone. This was the gemstone Noach hung in the ark to provide him with light. The Torah referred to this light in Genesis 6,15 צהר תעשה לתבה. Isaiah refers to it as אקדח, in Isaiah 54,12 where, speaking of the future of Israel he writes: ”I will make your battlements rubies and your gates of precious stones, i.e. לאבני אקדח.” The name is justified as it appears glowing like red-hot coals. A similar expression occurs also in Isaiah 50,11: “kindlers of fire.” The reason this stone was chosen to symbolise Levi was that the Levites illuminate the people by teaching them spiritual illumination, i.e. Torah, as we know from Deut. 33,10 יורו משפטיך ליעקב ותורתך לישראל, “they teach Your judgments to Yaakov and Your Torah to Israel.” We also know of Moses, who was of the tribe of Levi, that the whole house was filled with light when he was born as the Midrash (Shemot Rabbah 1,24) interpreted the words in Exodus there (Exodus 2,2) that “she (his mother) saw that he was good.” Furthermore, when Moses returned from Mount Sinai with the second sets of Tablets the Torah testified that the skin of his face emitted rays of light (Exodus 34,29). We have another verse (Kohelet 8,1) “a man’s wisdom lights up his face.” The positive value of this gemstone is that it is apt to enlighten the foolish, providing him with insights he never had. This is in addition to the general usefulness of that jewel in providing light just as does a lamp. People say that if one pounds this carbuncle into fine dust and mixes it with food or drink as one mixes certain medicinal herbs into the food it proves very capable of providing wisdom and opening up previously “closed” hearts.
Yehudah’s name was inscribed on the gemstone called נפך as we mentioned already. This jewel is known either as merkedy or zemurah in Arabic. Onkelos’ translation azmoragdin, (emerald) can support either one of these names. He chose a combination of these two words. As already mentioned, it is a greenish stone of high luster and represented his shame-facedness in accusing his daughter-in-law Tamar’s pregnancy as being the result of harlotry when he himself had fathered the child she was carrying (Genesis 38,26). Seeing that he overcame his embarrassment and made a public confession of his own involvement, this stone, i.e. its color, was chosen as appropriate for him. In addition he also had had to bear the shame, i.e. his face turning green, in the matter of having sold Joseph and his father suspecting him of this though the matter had never been spoken of. When Yaakov blessed Yehudah on his deathbed saying: “from the prey, my son, you elevated yourself,” he wanted him to know that he suspected him of having been involved in the deception which had made Yaakov call out in anguish: “a wild beast has torn Joseph to shreds (Genesis 37,33).” When hearing his father say that he considered Yehudah as having elevated himself, i.e. having exonerated himself from that guilt, his face was restored to its original colour after all these years. It then resembled the appearance of the emerald giving off a sparkle. It is also written of Yehudah (Genesis 49,8) “your hand is at the neck of your enemy,” and the outstanding feature of the gemstone emerald is that people wearing it experience that their enemies turn their neck towards them, i.e. that they attempt to flee. This is the reason this jewel is known as נפך. The Bible comments on Yehudah’s bravery in battle more than once, and it is written of David (Samuel I 18,7) that he defeated his enemies in their tens of thousands, Of the messiah it is written: (Isaiah 11,4) “with the spirit (breath) of his mouth he will kill the wicked.”
Issachar’s name was inscribed on a jewel called ספיר, sapphire, a jewel known as sephily of a blue colour. It had been assigned to Issachar because he was extremely wise and his tribe excelled in Torah knowledge. This has been attested to in Chronicles I 12,32. We have a tradition that the Tablets with the Ten Commandments were made of sapphire (Tanchuma Ki Tissa 26). We also find another reference to this jewel in Exodus 24,10 where the vision of G’d seen by the elders and the nobles is described as their observing with their mental eyes the appearance of bricks made of sapphire. It is a well known fact that the souls of Torah scholars are part of a whole bundle of souls beneath the throne of G’d’s attribute כבוד. This is derived from Ezekiel 1,26: “as the semblance of a throne, in appearance like sapphire.” The blue color of this jewel is not like the blue which denotes haughtiness similar to certain shades of red or green; on the contrary, it is a color symbolizing humility, modesty, a character trait equally becoming to both young and old. This is what Isaiah 57,15 meant when he wrote: “I dwell on high, in holiness; yet with the contrite and lowly in spirit.” The outstanding feature of this jewel is that it is good for one’s eyesight; this is the reason people have a habit of passing this jewel back and forth in front of their eyes. It was appropriate for Issachar as Torah also provides enlightenment. There is a popular saying that this jewel is useful in getting rid of all manner of pains and any swelling one experiences in any part of one’s body. The Torah too is a powerful remedy for all parts of the body. We have been told in Eyruvin 54 that if someone suffers from headaches the best remedy is to immerse oneself in the study of Torah.
The name of Zevulun was inscribed on the gemstone known as יהלום, diamond. This gemstone is known as pirle, same as bedolach. It is clear, transparent. It is to remind us of “white” silver, an allusion to the material wealth of the tribe of Zevulun. We know from Yaakov’s blessing of Zevulun in Genesis 49,13 that he was a great trader sending his ships far afield in order to bring home wealth from foreign lands. It was appropriate therefore that the stone bearing his name was the diamond. The special property of the diamond for man is that it helps one to go to sleep, something Leah referred to when she (the mother of Zevulun) said after he was born: “this time my husband will make his permanent home with me” (Genesis 30,20). [I believe what the author meant was that possession of diamonds allows people to sleep easy as they feel emotionally and economically secure. Ed.]
The name of the tribe of Dan was inscribed on a gemstone called לשם, known as opal, or ashtefassis. It shows a human face turned upside down, reminiscent of the time when the tribe of Dan attempted to reverse the norms of Judaism by appointing for themselves a non-Levite as religious leader (compare Judges 18,31). We find in Joshua 19,47 that a certain town previously called Leshem was renamed Dan in commemoration of the founding father of that tribe. This city became an integral part of the land of Israel.
The name of the tribe of Naftali was inscribed on a jewel known as שבו, agate. It is commonly known as turquoise. [The various names which I have spelled in italics appear to be the equivalents of these gems’ names in Spanish or old French during the time of the author. Ed.] Onkelos also translates it as טרקיא. The special property ascribed to that gemstone was that it “pulls” man while riding in carriages or riding horses and enables him to become successful as a driver or rider. This occurs through man and beast developing mutual affinity for each other while man sits in the saddle. It was appropriate for Naftali to be associated with this gemstone as at the time he was born his step-mother Rachel had said that she had prevailed in a struggle with the attribute of Justice and her sister and as a result her handmaid had born this son for her. Rachel also had to use all her abilities (she thought) in order to have a son at least through her handmaid (compare Genesis 30,8).
The gemstone bearing the name of Gad was the אחלמה, popularly known as crystal. This is why Onkelos translates the word as עין עגלא. A better known gemstone called lemon is similar to it but reddish in appearance. The reason this gemstone was used to symbolize Gad was that seeing the gemstone crystal is very common and everyone is familiar with it, the members of the tribe of Gad were also widely known as were the people who had been slain by this tribe in the wars of Israel against the Canaanites. This is the meaning of Deut. 33,20 וטרף זרעו קדקד , “tearing off arm, and even head.” The special property of this gemstone is that it reinforces the resolve of one’s heart when going to war and prevents one from becoming faint-hearted. The gemstone gives man strength. It is called אחלמה, as that word is connected to מלחמה, attributes needed to be successful in battle. The expression occurs in that sense in Isaiah 38,16: ותחלימני ותחיני, “You have restored me to health and have revived me.” The idea is that G’d made King Chiskiyah strong again. Another verse with a similar message is Job 39,4 where G’d speaks to Job about the health of the hinds, etc., saying יחלמו בניהם ירבו בבר, “their young are healthy (strong) able to grow up in the open fields.”
The gemstone on which the name of the tribe of Asher was inscribed is called תרשיש, better known as cariolica, topaz, chrysolite. Its color is close to that of oil (olive oil). Others say that its color is azure-blue (compare R' David Kimchi). Onkelos translates it as כרום ימא, aquamarine. The reason is that the color of the sea resembles that of azure-blue. The name Tarshish appears also as a destination in the ship hired by the prophet Jonah, presumably because these gems could be found in that country. The special property of this topaz is to facilitate in the digestion of foods. It is even more important if one first pulverizes it and mixes the powder into one’s food. It will then make a mass similar to a mixture of flour and oil. The Torah extols Asher’s land portion within the land of Israel as being particularly full of oil, i.e. rich soil as we know from Yaakov’s blessing in Genesis 49,20.
The gemstone bearing the name of the tribe of Joseph was called שהם, better known as onyx. The special property of this jewel is that its owners enjoy favor in the eyes of people. The letters in that stone also spell השם when read in a different order. This is an allusion to the verse in Genesis 39,2: “G’d was with Joseph and he became a successful man;” or, Genesis 39,24 “G’d made the warden of the prison like Joseph, etc.” Anyone who wears the jewel in the king’s palace will find that he becomes very successful and that his suggestions will be well received.
The name of the gemstone on which Binyamin’s name was inscribed was ישפה, better known as jasper. It is a multi-colored gem consisting of red, black, green. Binyamin had many contradictory thoughts about the sale of Joseph by his brothers, all of which are reflected in the different colours of the jasper. The special property of that stone is that it stops the flow of blood. The reason this gemstone was assigned to the tribe of Binyamin had to do with the founder of that tribe not being able to decide if to tell his father that Joseph was most likely alive, or to keep silent as he could not foresee how Yaakov would react to such information. In the end he controlled himself, stopped himself, and did not reveal what he knew. The word ישפה may be understood as two words, i.e. יש פה, “he has a mouth,” or words to that effect. The name of that stone alludes to the fact hat Binyamin deserved credit for keeping silent about what he knew his brothers had done to his older brother Joseph.
This completes the discussion about the twelve gemstones on the breastplate of the High Priest. All the details connected with the stones, the breastplate, the inscriptions, etc., are part and parcel of the detailed supervision G’d exercises over the fate of the Jewish people in all its aspects.
(4) I have seen in a book by Aristotle devoted to stones that the stones require the wearer of them to be pure in order for each of them to effectively carry out its special function, the properties we have listed above. If the wearer is ritually impure, they either lose their power altogether as far as he is concerned, or their power is greatly reduced. As soon as the wearer undergoes purification rites, the gemstone around his neck will recover its power. It is perfectly in order to accept what Aristotle says as there is no gemstone which does not contain some power given to it by celestial sources. Just as we have been taught in Bereshit Rabbah 10,7 that there is no herb on earth which does not have its counterpart in the celestial regions providing it with its individual mazzal, so the same is true of the precious stones. Having carefully absorbed what we have written about the gemstones in the garments of the High Priest you will note that he was surrounded by the names of the tribes of Israel both in front and behind, seeing these names were inscribed both on the breastplate and on the shoulder pieces of the ephod. [I suppose the fact that the ephod was closed from behind makes the whole garment appear as if it were worn on the back. Ed.] Whenever the High Priest put on his special vestments, he would put on the ephod and the breastplate at the same time, seeing that they were joined together and the Torah had instructed (verse 28) that the breastplate not be detached from the ephod. The band (belt) was tied together under the High Priest’s heart. The two shoulder-straps were inserted in the two rings at the upper end of the breastplate and two threads of blue wool cord were fed to beneath his armpits from the rings at the lower ends of the shoulder straps of the ephod. (5) A Kabbalistic approach: ...

No one truly knows the identity of each stone and there is little agreement upon the identities of each one today. I agree more with Rabbeinu Bachya's translation of the stones because they seem to have much more support behind them.

Aside from that, Rabbeinu Bachya perfectly points out and expertly shows how each stone correlates to a certain tribe. He also mentions the powers of each stone and how they were used in ancient times.

Bachya's words are put simply here:

"Ruby and Reuben. Reuben sinned by transposing the beds of his mother Leah and his father’s concubine Bilhah. The ruby’s red color represents the shame Reuben felt when admitting his misdeed.
Prase and Simeon. The tribe of Simeon sinned with the daughters of Moab and Midian, causing their faces to turn pale, adopting the greenish tinge of prase.
Carbuncle and Levi. The tribe of Levi devoted themselves to transmitting the teachings of G‑d to their brethren. The carbuncle’s brilliant sparkle symbolizes the Torah’s spiritual radiance.
Emerald and Judah. The emerald’s green color is reminiscent of Judah’s pale visage when his father incorrectly suspected him of murdering Joseph. The gem’s radiance represents Judah’s shining face when his father later praised him for saving Joseph from death.
Sapphire and Issachar. The tribe of Issachar was renowned for its greatness in Torah study. They are therefore associated with sapphire, the material from which the two tablets were formed.
Pearl and Zebulun. The tribe of Zebulun engaged in commerce, amassing great wealth. The white pearl resembles the color of silver coins.
Leshem and Dan. The streaks within the leshem appear similar to a backward human face. This alludes to the tribe of Dan’s “backward” conduct in fashioning an idolatrous image.
Turquoise and Naphtali. In days of old, turquoise was commonly carried by members of the cavalry. The closeness between the rider and his horse is associated with the name Naphtali, Hebrew for connection.
Crystal and Gad. Just as crystals are widespread minerals, the tribe of Gad were numerous and well-known.
Chrysolite and Asher. Chrysolite takes on the complexion of olive oil, a substance found in abundance in the land of the tribe of Asher.
Onyx and Joseph. The letters of the Hebrew name for onyx, shoham, can be rearranged to spell Hashem (“the Name”), a common way of referring to G‑d. This alludes to Joseph’s Divinely sourced success in the home of Potiphar.
Jasper and Benjamin. After Joseph’s sale into slavery by his brothers, Benjamin—who was not present at the time—deliberated whether or not he should reveal his brother’s whereabouts to his father, Jacob. This back-and-forth internal dialogue is reflected in jasper’s numerous colors."

Question #4: Why is it called the breastplate of decision/judgement or "חֹ֤שֶׁן מִשְׁפָּט֙"?

(א) חשן משפט. שֶׁמְּכַפֵּר עַל קִלְקוּל הַדִּין. דָּ"אַ, מִשְׁפָּט שֶׁמְּבָרֵר דְּבָרָיו וְהַבְטָחָתוֹ אֱמֶת, דריש"נטנט בְּלַעַז; שֶׁהַמִּשְׁפָּט מְשַׁמֵּשׁ שָׁלֹשׁ לְשׁוֹנוֹת, דִּבְרֵי טַעֲנוֹת הַבַּעֲלֵי דִּינִים וּגְמַר הַדִּין וְעֹנֶשׁ הַדִּין, אִם עֹנֶשׁ מִיתָה, אִם עֹנֶשׁ מַכּוֹת, אִם עֹנֶשׁ מָמוֹן, וְזֶה מְשַׁמֵּשׁ לְשׁוֹן בֵּרוּר דְּבָרִים, שֶׁמְּפָרֵשׁ וּמְבָרֵר דְּבָרָיו:

(1) חשן משפט THE BREAST-PLATE OF JUDGMENT — it was so called because it atoned for any error in judgment (cf. Zevachim 88b; Jerusalem Talmud Yoma 7:5). Another explanation of why it is called “the breast-plate of משפט”, is because it makes its statements clear (definite — so that there can be no doubt about their meaning) and its promise is true; discernment in old French, (sentence of judgment). Because the word משפט is used in three senses: the contentions of the parties to the law-suit, the pronouncement of the sentence and the punishment attendant on the sentence, whether it be punishment of death or punishment of flagellation or punishment involving a monetary payment; here it is used in the sense of making its statements definite, so that this is the breast-plate with the Urim and Thummim which explains and makes its statement clear.

According to Rashi, it was called this because it atoned for any error in judgement, and was able to make its statements clear and definite in a way that there would be no doubt in their meaning.

ועשית חשן משפט, פרש"י שמברר דבריו והבטחתו אמת, המשפט הוא הבירור בין שני צדדי הספק, שני אנשים נגשים לריב, והמשפט מברר מי הצודק כמו שמבואר אצל הבדל לשונות ריב, דין, משפט, ולפני האורים יגישו שני צדדי הספק, כמו האלך למלחמה אם אחדל, והם מבררים ימי הצודק, ועז"א ושאל לו במשפט האורים, ועיין ברמזי הבגדים מ"ש בזה, כמעשה אפד, מעשה חושב ומחמשת המינים:

The mishpat is discerning between the two sides of doubt. Two people engaged in a quarrel, and the choshen discerns who is right. The way it is explained through different words of quarrel, judgement, and trial. Before Urim they will present the two sides of doubt. Shall I go to war or not? And they sort out who is right. On this they said "and he will ask to himself the discernment of the Urim." ... And from the five species of animals that give these pigments.

Malbim seems to agree with Rashi, he only further elaborates on Rashi's ideas.

Question #5: When did Jews stop using the Choshen? Why?

הרחיבה שאול נפשה ופערה פיה לבלי חק וירד הדרה והמונה ושאונה ועלז בה משמתו נביאים הראשונים מאן נביאים הראשונים אמר רב הונא זה דוד ושמואל ושלמה רב נחמן אמר בימי דוד זימנין סליק וזימנין לא סליק שהרי שאל צדוק ועלתה לו שאל אביתר ולא עלתה לו שנאמר (שמואל ב טו, כד) ויעל אביתר מתיב רבה בר שמואל (דברי הימים ב כו, ה) ויהי לדרוש אלהים כל ימי זכריה המבין בראות אלהים מאי לאו באורים ותומים לא בנביאים ת"ש משחרב בהמ"ק ראשון בטלו ערי מגרש ופסקו אורים ותומים ופסק מלך מבית דוד ואם לחשך אדם לומר (עזרא ב, סג) ויאמר התרשתא להם אשר לא יאכלו מקדש הקדשים עד עמוד כהן לאורים ותומים [אמור לו] כאדם שאומר לחבירו עד שיחיו מתים ויבא משיח בן דוד אלא אמר רב נחמן בר יצחק מאן נביאים הראשונים לאפוקי מחגי זכריה ומלאכי דאחרונים נינהו דת"ר משמתו חגי זכריה ומלאכי נסתלקה רוח הקודש מישראל ואע"פ כן היו משתמשים בבת קול שפעם אחת היו מסובין בעליית בית גוריא ביריחו נתנה עליהן בת קול מן השמים ואמרה יש בכם אדם אחד שראוי שתשרה שכינה עליו אלא שאין דורו ראוי לכך נתנו עיניהם בהלל הזקן וכשמת הספידוהו הי חסיד הי עניו תלמידו של עזרא ושוב פעם אחרת היו מסובין בעלייה ביבנה נתנה להן בת קול מן השמים ואמרה להן יש בכם אדם א' שראוי שתשרה שכינה עליו אלא שאין דורו זכאין לכך נתנו עיניהם בשמואל הקטן וכשמת הספידוהו הי עניו הי חסיד תלמידו של הלל ואף הוא אמר בשעת מיתתו שמעון וישמעאל לחרבא וחברוהי לקטלא ושאר עמא לביזא ועקן סגיאין עתידין למיתי על עמא ואף על ר' יהודה בן בבא בקשו לומר הי חסיד הי עניו אלא שנטרפה שעה שאין מספידין על הרוגי מלכות

the netherworld has enlarged her desire, and opened her mouth without measure, and down goes their glory and their tumult and their uproar, and he who rejoices among them” (Isaiah 5:14). Their punishment is that they shall descend into the netherworld. § The mishna taught: From the time when the early prophets died, the Urim VeTummim was nullified. The Gemara poses a question: Who are the early prophets? Rav Huna says: This is referring to David, and Samuel, and Solomon, and after their death the Urim VeTummim was no longer used. Rav Naḥman said: In the days of David there were times an answer rose up for them from the Urim VeTummim and there were times an answer did not rise up, i.e., they did not receive an answer. The proof for this is that Tzadok, the High Priest in David’s time, asked the Urim VeTummim and an answer rose up for him, whereas Abiathar asked and an answer did not rise up for him, as it is stated: “And Abiathar went up” (II Samuel 15:24), and he was removed from serving as the High Priest as a result. Rabba bar Shmuel raises an objection: The verse states concerning Uzziah: “And he set himself to seek God in the days of Zechariah, who had an understanding of the vision of God” (II Chronicles 26:5). What, is the verse not stating that Uzziah would seek God by asking questions of the Urim VeTummim, despite the fact that he lived after the time of Solomon? The Gemara rejects this claim: No, he would seek God by asking questions of the prophets, but not of the Urim VeTummim. The Gemara suggests: Come and hear a proof from a baraita (Tosefta 13:2) with regard to when the Urim VeTummim ceased: From the time when the First Temple was destroyed, the cities with fields that were allocated to the Levites were nullified, and the Urim VeTummim ceased, and the monarchy ceased from the house of David. And if a person would whisper to you saying that the Urim VeTummim was still extant, as it states with regard to when the Second Temple first stood: “And the Tirshatha said to them that they should not eat of the most sacred things, until there stood a priest with the Urim VeTummim (Ezra 2:63), which seems to indicate that they merely had to wait until the Second Temple was built for the reappearance of the Urim VeTummim; you should say to him that this is not referring to an expectation of a short-term development, but it is like a person who says to his friend, with regard to something that will occur in the distant future: Until the dead live and the Messiah, the son of David, comes. In any case, the baraita indicates that the Urim VeTummim ceased only from the time when the First Temple was destroyed, and not in the time of Solomon. Rather, Rav Naḥman bar Yitzḥak said: Who are the early prophets, with regard to whom it states that use of the Urim VeTummim ceased immediately after their death? This term early prophets serves to exclude Haggai, Zechariah, and Malachi, who are the latter prophets. The Urim VeTummim was used throughout the First Temple period, up to, but not including, their time. As the Sages taught in a baraita (Tosefta 13:3): From the time when Haggai, Zechariah, and Malachi died the Divine Spirit departed from the Jewish people, as these three were considered to be the last prophets. And even after the Urim VeTummim ceased to exist, they would nevertheless still make use of a Divine Voice to receive instructions from Above, even after this time. For on one occasion the Sages were reclining in the upper story of the house of Gurya in Jericho. A Divine Voice from Heaven was issued to them, and it said: There is one person among you for whom it is fitting that the Divine Presence should rest upon him as a prophet, but his generation is not fit for it; they do not deserve to have a prophet among them. The Sages present directed their gaze to Hillel the Elder. And when he died, they eulogized him in the following manner: Alas pious one, alas humble one, student of Ezra. And again, on another occasion several generations later, the Sages were reclining in an upper story of a house in Yavne, and a Divine Voice from Heaven was issued to them, and said: There is one person among you for whom it is fitting that the Divine Presence should rest upon him, but his generation is not fit for it. The Sages present directed their gaze to Shmuel HaKatan. And when he died, they eulogized him in the following manner: Alas humble one, alas pious one, student of Hillel. And he too, Shmuel HaKatan, said the following statement of divinely inspired prediction at the time of his death: Shimon, i.e., Rabban Shimon ben Gamliel, and Yishmael, i.e., Rabbi Yishmael ben Elisha the High Priest, are slated for the sword, and their colleagues for killing, and the rest of the people for plunder, and great troubles are destined to befall the people. The Gemara relates: And they also sought to say about Rabbi Yehuda ben Bava, when eulogizing him: Alas pious one, alas humble one, but the moment was disturbed and they could not do so. That is because eulogies are not given for those killed by the monarchy, which was Rabbi Yehuda ben Baba’s fate, in order not to arouse the monarchy’s wrath.

In Sotah 48b it is said that when the "early prophets died Urim and Thummim were nullified". Now this makes us infer that due to Urim and Thummim being nullified, so was the Choshen.

Therefore, we stopped using it because it stopped working.

Question #6: Where is the oldest excavated Choshen?

"this magical form of communicating with G-d was lost when the Babylonians sacked Jerusalem. Nevertheless, a remnant reportedly remains. There is speculation that one of the [sardonyx] stones has been found in South Africa among the descendants of a crusader knight who came to the Holy Land. If the speculation is proven to be true, only then can we truly begin to grasp what it really looked like" (12 Stones).
This website discusses where there is potential for a choshen to be found. But to this day there have been no ancient breastplates found in any excavations. Nor any remnants have been found.

Question #7: Could we create a choshen and use it today?

This question was answered expertly by Rabbi Yirmiyahu Ullman when responding to a question asked by a man named Alan. The letter is found here.
Dear Rabbi,
I am very intrigued by the breast plate of the High Priest and was wondering whether it could be fashioned nowadays or whether it was only something of the past, or otherwise relevant only if there is a Temple or priestly service?
Dear Alan,
I agree, the High Priest’s breast plate was not merely ornamentally exquisite, it was fantastically oracular.
It was comprised of 12 different types of precious gem stones arranged in four rows, where each stone corresponded to a particular tribe whose name was engraved on it, together with the names of the patriarchs and the term “Tribes of G-d” – together including all of the letters of the Hebrew alef-bet.
When the High Priest would direct queries of great import to G-d, the letters on these stones would illuminate in succession in order to convey to the High Priest prophetic messages from G-d, which he deciphered and then communicated to the people.
This breast plate is not just a relic of the past, nor is its fashioning dependent on the existence of the Temple or the priestly service. Rather, theoretically, if the necessary materials could be acquired and it could be constructed according to specification, which our sources amply describe, it could be fashioned even in the absence of the Temple and its service.
Interestingly, the main impediment to making the breastplate would seem to be the lack of a special worm called the “shamir”.
Based on a precise reading of the verses (Ex. 28:11; 39:13) in the Torah describing the preparation of these precious stones for the breast plate, the Talmud (Sota 48b) states that the wording on them be not merely written but rather engraved, and not with an implement that would cause wasteful shavings but rather in a way that would preserve the integrity of the stones.
This was accomplished through this unique worm, which the Talmud says was created specifically for this purpose, as it was able to cut through stone in a non-chisel like fashion. The relevant letters were thus stenciled onto the stones, and the shamir would follow the lines and thereby carve the words into the gems of the breast plate.
The problem is that the same teaching tells us that since the Temple was destroyed, the shamir was lost. The result of this is that if the shamir is the only way to cut and engrave the stones, its absence would preclude the fashioning of the breast plate.
However, if this is so, it raises the following question: Since the shamir was lost after the destruction of the First Temple, how did they prepare the stones of the breast plate in the Second Temple where there certainly was a High Priest with all the priestly garments, including the breast plate?
One might suggest that the breast plate from the First Temple remained until the 2nd, as in fact we find that the Talmud (Megilla 12a) says that King Achashverosh wore it during his great banquet, in which he also used and displayed other plundered vessels from the First Temple. But even though it apparently survived the Babylon destruction and exile and was later sequestered by the Persians, it is very unlikely that it made its way back to Israel under the auspices of Cyrus. The first chapter of the Book of Ezra enumerates in great detail the type and number of even minor vessels that were returned, but there is no mention of the breast plate.
So the question remains: How were the stones of the breast plate fashioned in the Second Temple?
It is quite intriguing that Rambam (Klei HaMikdash 9:6) writes in great detail the halachic specifications of the breast plate, its stones, their positioning and setting in the breast plate etc., but makes no mention of the requirement of the shamir. The Mishna l’Melech commentary on Rambam notes this curious omission and wonders why Rambam would leave out what would seem to be such an important point regarding the preparation of the stones.
However, later commentaries (Chatan Sofer ch. 1 sec. 6 and Hitorerut Teshuva 1:282) conclude from these several considerations that the use of the shamir must be only an “ideal” requirement, but in its absence, regular engraving is permitted, which would explain why Rambam left it out and this must be how the stones of the breast plate were fashioned in the Second Temple.
Accordingly, these commentaries posit that it would be permitted and possible to prepare the breast plate even today without the Temple or its service.

The simple answer is yes. We are permitted to create another Choshen. But, I don't believe there would be very much of a reason to because it wouldn't hold the same powers as it once had.

Question #8: Are there any midrashim on the Choshen?

After great lengths of research online, I couldn't find any midrashim that include the Choshen or ephod or Urim Vethummim. I bet there are many, but I couldn't find any... If you know of any, please feel free to comment them!
