Segment 1א׳

תָּא חֲזֵי, בְּגִינֵיהּ דְּיַעֲקֹב אִתְקְיַּים עַלְמָא, וְאִי תֵימָא הָא בְגִינֵיהּ דְּאַבְרָהָם, כְּמָה דְאַתְּ אָמֵר, (בראשית ב) בְּהִבָּרְאָם, אַל תִּקְרֵי בְּהִבָּרְאָם אֶלָּא בְּאַבְרָהָם. אֶלָּא בְּגִינֵיהּ דְּיַעֲקֹב אִתְקְיַּים אַבְרָהָם, דִּכְתִיב, (ישעיהו כ״ט:כ״ב) כֹּה אָמַר ה' אֶל בֵּית יַעֲקֹב אֲשֶׁר פָּדָה אֶת אַבְרָהָם. וּמִקַּדְּמַת דְּנָא הֲוָה קוּדְשָׁא בְּרִיךְ הוּא בָּנֵי עָלְמִין וְחָרִיב לוֹן, כֵּיוָן דְּאֲתָא יַעֲקֹב מִנֵּיהּ אִשְׁתַּכְלָלוּ עָלְמִין, וְלָא אִתְחָרָבוּ כְּקַדְמִיתָא, הֲדָא הוּא דִכְתִיב, (ישעיהו מ״ג:א׳) כֹּה אָמַר ה' בֹּרַאֲךָ יַעֲקֹב וְיֹצֶרְךָ יִשְׂרָאֵל וְגו'.

Observe that it was for the sake of Jacob that the world became firmly established. (For though we have said elsewhere that it was for the sake of Abraham, the truth is that it was for the sake of Jacob that Abraham was firmly established, as it is written: “Thus saith the Lord, concerning the house of Jacob who redeemed Abraham” (Is. 29, 22).) For at first God built up worlds and destroyed them, and only when Jacob came did the worlds take their final form, and were not again demolished as heretofore. So Scripture says: “But now thus saith the Lord that created thee, O Jacob, and he that formed thee, O Israel” (Is. 43, 1).

Segment 2ב׳

תָּא חֲזֵי מַה כְּתִיב, (שמות ד׳:כ״ג) בְּנִי בְּכוֹרִי יִשְׂרָאֵל, וּכְתִיב (שם) שַׁלַּח אֶת בְּנִי וְיַעַבְדֵנִי, יִשְׂרָאֵל אִקְרֵי בֵּן לְקוּדְשָׁא בְּרִיךְ הוּא, בְּגִין דְּאִתְדָּבַּק בֵּיהּ, כְּמָה דְאַתְּ אָמֵר, (משלי ל׳:ד׳) מַה שְּׁמוֹ וּמַה שֵּׁם בְּנוֹ כִּי תֵדָע.

Israel is also called “son” to God, as it is written: “Israel is my son, my firstborn”, also, “Let my son go that he may serve me” (Ex. 4, 22-23). There is also the same allusion in the verse: “What is his name, and what is his son’s name, if thou knowest” (Prov. 30, 4).’

Segment 3ג׳

לֵאָה, כַּד אוֹלִידַת לִרְאוּבֵן מַה כְּתִיב, (בראשית כ״ט:ל״ב) וַתִּקְרָא אֶת שְׁמוֹ רְאוּבֵן. רְאוּבֵן סְתָם, בְּגִין דְּאִתְכְּלִיל בִּתְלַת סִטְרִין מִתְחַבְּרָן כְּחֲדָא, שִׁמְעוֹן וְלֵוִי. מַאי טַעְמָא לֵוִי, כְּמָה דְאַתְּ אָמֵר, (מלכים א ז) לֹיוֹת, חִבּוּרָא דְכָל סִטְרִין.

AND SHE CALLED HIS NAME REUBEN (lit. see, a son). She did not give him a more specific name, because he was to form a group with the other two, Simeon and Levi. The name Levi, being akin to the term loyoth (joining) (I Kings 7, 30), signifies the perfect combination of them into one scheme.
