(א) ויקרא משה להושע וגו' . התפלל עליו יה יושיעך מעצת מרגלים:
(1) "And Moses called to Hoshea etc." - [Moses] prayed to G-d about [Hoshea] that [he] should be saved from the counsel of the spies.
(א) ויאמר משה אל יהושע נראה מכאן כי משה מיום היותו לפניו היה קורא אותו יהושע, וכן כתוב (להלן לב יז) וישמע יהושע את קול העם. והכתוב שאמר בענין המרגלים ויקרא משה להושע בן נון יהושע (במדבר יג טז), למבראשונה ידבר, הודיענו כי זה הושע בן נון אשר בחרו במרגלים הוא אשר קראו משה יהושע. וכדברי רבותינו (סוטה לד:) שאמר יה יושיעך מעצת מרגלים, להגיד כי בעבור זה המעשה שהיה משה יודע שהוא עתיד ללכת עם המרגלים קרא לו השם הזה. או נאמר כי אז קבע לו משה אותו השם בפני העדה שלא יקרא שמו עוד הושע ויהיה שמו יהושע:
Moses said to Joshua: Apparently Moses called him Joshua from the day when he first began to serve him; evidently "Moses changed the name of Hoshea son of Nun to Joshua" (Numbers 13:16) is telling us that the Hosea selected to be among the spies is the one whose name Moses had changed. The Midrash says Moses changed his name to make it a prayer, "May God preserve you from the counsels of the spies," which tells us that Moses knew about the incident in advance. Or perhaps at that time Moses made the name change public so that from that time on everyone would call him Joshua instead of Hoshea.
(2) ויקרא משה להושע בן נון יהושע, “Moses named Hoseah son of Nun Joshua.” According to the plain meaning of the text his name was changed, as he had been the commander of the army in the battle against Amalek. He had acquired an international reputation as a result of that encounter. Moses changed his name so that he would not be singled out as a target for the Canaanites. After all, they had never seen him, had only heard about him.
(א) ויקרא משה להושע בן נון יהושע - לא עתה קרא אותו כן, שהרי כבר קודם לכן נקרא יהושע אלא כך פירושו: הושע בן נון שאמרנו למעלה שנקרא כן בבית אביו הוא אותו שקרא משה [יהושע] כשנעשה משרתו והפקידו על ביתו, שכך היה מנהגם כמו: ויקרא פרעה שם יוסף צפנת פענח. ויקרא לדניאל די שמיה בלטשצר כשם אלהיה.
(1) And Moses called Hoshea son of Nun Joshua: This does not mean that the people from then on called this man Joshua. It means that the man who had been referred to as Hosheah son of Nun in his father’s house was the one whom Moses now referred to as Joshua. The change had occurred already at the time when Moses appointed this man to be his personal valet. It was customary to change the names of people who were promoted in rank. We find this the first time when Pharaoh changed Joseph’s name to Tzofnat Paneach (Genesis 41,45) We find it again in Daniel 1,6 when Nevuchadnezzar’s chief officer changed Daniel’s name to Belteshazzar. This had been a reference to a Babylonian idol so named. The first time Joshua’s name had been changed was in Exodus 24,13.
( ד"א וישמע יתרו, מתחלה לא היו קוראין לו אלא יתר, שנאמר (שמות ד) וילך משה וישב אל יתר חותנו, וכשעשה מעשים טובים הוסיפו לו אות אחת. וכן אתה מוצא באברהם, שמתחלה לא היו קוראין אותו אלא אברם, וכשעשה מעשים טובים הוסיפו לו אות אחת, ונקרא שמו אברהם. וכן אתה מוצא בשרה, שמתחלתה היו קוראין אותה שרי, וכשעשתה מעשים טובים הוסיפו לה אות אחת גדולה ונקראת שמה שרה. וכן אתה מוצא ביהושע, [שמתחלה היו קוראין אותו הושע, וכשעשה מעשים טובים הוסיפו לו אות אחת ונקרא יהושע,] שנא' (במדבר יג) ויקרא משה להושע בן נון יהושע. ויש אחרים שפחתו מהם; יש לך ללמד מעפרון, שמתחלה היו קוראין אותו עפרון, וכששקל הכסף מיד אברהם פחתו אות אחת משמו, שנאמר וישמע אברהם אל עפרון וישקול אברהם לעפרן את הכסף, עפרן כתיב. וכן אתה מוצא ביונדב, שמתחלה היו קוראין אותו יהונדב, וכשבא לאותו מעשה, פחתו לו אות אחת ונקרא יונדב, שנאמר (דה"ב כ) בהתחברך לרשע פרץ ה' מעשיך. מכאן אמרו חכמים, אל יתחבר אדם לרשע אפילו לקרבו לתורה.
In the beginning, Jethro was called "Yether," viz. (Exodus 4:18) "And Moses went and he returned to Yether, his father-in-law," and when he "added" good deeds (to himself), a letter (vav) was added to his name. And thus do you find with Avraham. In the beginning he was called "Avram," and when he "added" good deeds, a letter (heh) was added to his name and he was called "Avraham." And thus do you find with Sarah. In the beginning she was called "Sarai," and when she "added" good deeds, a "great" letter (heh) was added to her name and she was called "Sarah." And thus do you find with Yehoshua, viz. (Numbers 13:16) "And Moses called Hoshea the son of Nun Yehoshua." And there are others whose name was diminished, e.g., Efron. In the beginning he was called "Efron," but when he took the money from Abraham, a letter was dropped from his name, viz. (Genesis 23:16) "and Abraham hearkened to Efron," "and Abraham gave the money to Efron." And thus do you find with Yonadav. In the beginning he was called "Yehonadav," but after "that deed" a letter was dropped from his name and he was called "Yonadav," as it is written (II Chronicles 20:37) "When you befriended Achazyahu, etc." — whence the sages ruled: Let one not befriend an evildoer, even to draw him close to Torah.
Having mentioned the changing of Jacob’s name, the Gemara addresses the changing of the names of Abraham and Sarah. What is the meaning of changing Abram’s name to Abraham? As it is stated: “Abram is Abraham” (I Chronicles 1:27). The Gemara explains: Initially he became a father, a minister, and prominent person, only to Aram, so he was called Abram, father [av] of Aram, and ultimately with God’s blessing he became the father of the entire world, so he was called Abraham, father of the masses [av hamon], as it is stated: “I have made you the father of a multitude of nations” (Genesis 17:5). Similarly, what is the meaning of changing Sarai’s name to Sarah? The same concept applies to Sarai as to Abram: Sarai is Sarah.” The Gemara explains: Initially she was a princess only to her nation: My princess [Sarai], but ultimately she became Sarah, a general term indicating that she was princess for the entire world. Also, with regard to Abraham’s name, bar Kappara taught: Anyone who calls Abraham Abram transgresses a positive mitzva, as it is stated: “And your name will be Abraham” (Genesis 17:5). This is a positive mitzva to refer to him as Abraham. Rabbi Eliezer says: One who calls Abraham Abram transgresses a negative mitzva, as it is stated: “And your name shall no longer be called Abram, and your name will be Abraham, for I have made you the father of a multitude of nations” (Genesis 17:5). The Gemara asks: But if we consider these obligatory statements, then from here we must infer that one who calls Sarah Sarai also transgresses a positive or negative mitzva. The Gemara answers: There in the case of Sarah, it is not a general mitzva, rather the Holy One, Blessed be He, said to Abraham alone: “And God said to Abraham, your wife Sarai, you shall not call her name Sarai; rather, Sarah is her name” (Genesis 17:15). In contrast, this is stated regarding Abraham in general terms: “Your name shall no longer be called Abram.” Again, the Gemara asks: But if that is so, one who calls Jacob Jacob, about whom it is written: “Your name shall no longer be Jacob, but Israel” (Genesis 32:29), also transgresses a mitzva. The Gemara answers: It is different there, as the verse reverts back and God Himself refers to Jacob as Jacob, as it is written before his descent to Egypt: “And God said to Israel in the visions of the night, and said, Jacob, Jacob, and he said, ‘Here I am’” (Genesis 46:2).
The Gemara answers: As taught by Ulla, as Ulla said: Wherever one’s name and his father’s name are mentioned with regard to prophecy, it is known that he was a prophet the son of a prophet, and therefore his father’s name is also mentioned. And wherever his name is mentioned but not his father’s name, it is known that he was a prophet but not the son of a prophet. Similarly, wherever his name and the name of his city are specified, it is known that he was from that particular city, and wherever his name is mentioned but not the name of his city, it is known that he was from Jerusalem.
(ח) וְזֶה זוֹכִין עַל־יְדֵי עֵסֶק הַתּוֹרָה. כִּי הַתּוֹרָה הִיא שְׁמוֹ שֶׁל הַקָּדוֹשׁ־ בָּרוּךְ־הוּא, וְהַשֵּׁם הוּא הַכְּלִי שֶׁל הַדָּבָר, שֶׁבְּהַשֵּׁם הַזֶּה נִגְבָּל הַחִיּוּת שֶׁל הַדָּבָר הַזֶּה, כְּמוֹ שֶׁכָּתוּב (בראשית ב׳:י״ט): נֶפֶשׁ חַיָּה הוּא שְׁמוֹ, שֶׁבְּהַשֵּׁם נִגְבָּל הַנֶּפֶשׁ וְהַחִיּוּת שֶׁל כָּל דָּבָר. וְעַל כֵּן כְּשֶׁקּוֹרִין אֶת הָאָדָם בִּשְׁמוֹ, הוּא מְזֻמָּן תֵּכֶף אֶצְלוֹ, מֵחֲמַת שֶׁבְּהַשֵּׁם נִגְבָּל כָּל הַנֶּפֶשׁ וְהַחִיּוּת שֶׁלּוֹ.
(8) We merit this through Torah study. This is because the Torah is the Name of God, and the name of a thing is its vessel; within this name is contained the life force of that thing. As it is written, “living soul that is its name” (Genesis 2:19)—contained in the name of each thing is its soul and life force. This is why when we call a person by his name, we gain his attention immediately, because his total soul and life force are contained within his name.
