These Names
(א) וְאֵ֗לֶּה שְׁמוֹת֙ בְּנֵ֣י יִשְׂרָאֵ֔ל הַבָּאִ֖ים מִצְרָ֑יְמָה אֵ֣ת יַעֲקֹ֔ב אִ֥ישׁ וּבֵית֖וֹ בָּֽאוּ׃
(1) These are the names of the sons of Israel who came to Egypt with Jacob, each coming with his household:
וְאֵלֶּה שְׁמוֹת בְּנֵי יִשְׂרָאֵל הַבָּאִים מִצְרַיְמָה יַעֲקֹב וּבָנָיו אִישׁ וּבֵיתוֹ בָּאוּ, שְׁקוּלִים הֵם יִשְׂרָאֵל כִּצְבָא הַשָּׁמַיִם, נֶאֱמַר כָּאן שְׁמוֹת, וְנֶאֱמַר בַּכּוֹכָבִים שֵׁמוֹת, שֶׁנֶּאֱמַר (תהלים קמז, ד): מוֹנֶה מִסְפָּר לַכּוֹכָבִים לְכֻלָּם שֵׁמוֹת יִקְרָא. אַף הַקָּדוֹשׁ בָּרוּךְ הוּא כְּשֶׁיָּרְדוּ יִשְׂרָאֵל לְמִצְרַיִם מָנָה מִסְפָּרָם כַּמָּה הָיוּ, וּלְפִי שֶׁהֵם מְשׁוּלִים לַכּוֹכָבִים קָרָא שֵׁמוֹת לְכֻלָּם, הֲדָא הוּא דִכְתִיב: וְאֵלֶּה שְׁמוֹת בְּנֵי יִשְׂרָאֵל וגו'.
And these are the names of the Children of Israel who came to Egypt, Jacob and his sons, each man and his household came - Israel is comparable to the multitude of the heavens, here it is said names, and it is said of stars names, as it is said (Psalms 147:4): "He counteth the number of the stars; He giveth them all their names," even the Holy One Blessed is He, when Israel descended to Egypt, counted how many they were, and because they are compared to the stars, He gave them all names, as it is written: "And these are the names of the Children of Israel, etc."
(א) ואלה שמות בני ישראל. אַעַ"פִּ שֶׁמְּנָאָן בְּחַיֵּיהֶם בִּשְׁמוֹתָם, חָזַר וּמְנָאָם בְּמִיתָתָם, לְהוֹדִיעַ חִבָּתָם, שֶׁנִּמְשְׁלוּ לְכוֹכָבִים, שֶׁמּוֹצִיאָם וּמַכְנִיסָם בְּמִסְפַּר וּבִשְׁמוֹתָם (שמות רבה), שֶׁנֶּ' "הַמּוֹצִיא בְמִסְפָּר צְבָאָם לְכֻלָּם בְּשֵׁם יִקְרָא" (ישעיהו מ'):
(1) ואלה שמות בני ישראל NOW THESE ARE THE NAMES OF THE CHILDREN OF ISRAEL — Although scripture has already enumerated them by name whilst they were living, when they went down into Egypt (Genesis 46:8-27), it again enumerates them when it tells us of their death, thus showing how dear they were to God — that they are compared to the stars which also God brings out and brings in by number and name when they cease to shine, as it is said, (Isaiah 40:26) “He bringeth out their host by number, He calleth them all by name” (Exodus Rabbah 1:3; Tanchuma Yashan 1:1:2).

(א) ואלה שמות בני ישראל כו' ראובן כו' (שמות א, א-ב). כי הנה שמות השבטים הקדושים כאשר תראה השם של כל אחד על מה נקרא בשם זה ראובן כי ראה ה', כי אתה יאהבני אישי (בראשית כט, לב) שמעון כי שמע ה' וכו' (שם לג) לוי הפעם ילוה אישי אלי (שם לד) הנה באמת חס ושלום אי אפשר לומר שהשבטים יהיו נקראים על שום תאוה גשמיות כגון ראובן כו', וכן שאר השבטים כגון יששכר ואשר. הנה באמת שמות השבטים מורים על העלאות כל התאוה לה' לבדו. בראובן העלה כל התאות שבין איש לאשתו להבורא יתברך שמו וכן שמעון וכן לוי מורה עליות כל התחברות להבורא יתברך לכך נקראים השבטים מטות מלשון מטהו מחלון לחלון, כלומר שהתאות הגשמיות העלהו להבורא יתברך. וזהו ואלה שמות בני ישראל, השמות בעצמם מורים על עליות כל הדברים להבורא יתברך ויתעלה זכרו:

(1) Exodus 1,1. “And these are the names of the tribes of ‎Israel; Reuven, etc.”; the reason why the names of the holy ‎tribes are enumerated once more is because their qualifications as ‎being part of the twelve holy tribes is already alluded to in their ‎names, as we shall see. Reuven was called by that name as his ‎mother had proclaimed at his birth (Genesis 29,32) “G’d has seen ‎my distress; now my husband will love me.” When Leah bore ‎Shimon (verse 13 ibid), she gave thanks to G’d to listening to her ‎prayer. When Levi was born (verse 34) she expressed her ‎conviction to G’d that from then on her husband would devote ‎more of his time to her. Both Shimon’s name from the word ‎שמע‎ ‎‎“to hear,” and Levi’s name from the word ‎ללוות‎, “to keep ‎company with,” reflect the connection to G’d that Leah saw in ‎these sons as accompanying them already from birth. When the ‎reader will once more peruse the relevant chapter in Parshat ‎Vayetze‎‎ he will see that all the names bore testimony to the ‎mothers seeing in these sons being born a gift of G’d, so that it ‎was no more than natural that the sons when growing up would ‎excel in their service to G’d, i.e. they would qualify for the title: ‎קדוש‎, “holy.”
It would be quite inconceivable that the ‎matriarchs would have named their children in commemorating a ‎physical craving of theirs as having been fulfilled. The fact that ‎the Torah refers to these tribes, i.e. ‎שבטים‎, not by their secular ‎name, but calls them ‎מטות‎, a word reminding us of someone, i.e. ‎G’d leaning out of a window to see what goes on beneath him. ‎According to our author it is used to describe physical cravings ‎which have been sublimated to become spiritual cravings.‎
