創世記 29:34

הפעם ילוה אישי THIS TIME WILL MY HUSBAND BECOME ATTACHED TO ME — Because the Matriarchs were prophetesses and knew that twelve tribes would issue from Jacob and that he would have four wives, she said, “From now he will have no fault to find with me, for I have assumed my full share in giving him children” (Midrash Tanchuma, Vayetzei 9). על כן THEREFORE — Wherever in the case of the names given to Jacob’s sons the word “therefore” is used, that tribe had a numerous population (Genesis Rabbah 71:4), Levi forming an exception, because the Ark decimated them. קרא שמו לוי [THEREFORE] WAS HIS NAME CALLED LEVI (literally, he called his name) — Of all of them (the sons) it is written “And she called”, but of this one Scripture writes “he called!” There is a Midrashic statement in Deuteronomy Rabbah that the Holy One, blessed be He, sent Gabriel who brought him (Levi) into His presence. He called him by this name and gave him the twenty-four perquisites with which the priesthood was favoured, and because He gave him these perquisites as an accompaniment (לוהו) He called him Levi (accompanied).

וַתַּ֣הַר עוֹד֮ וַתֵּ֣לֶד בֵּן֒ וַתֹּ֗אמֶר עַתָּ֤ה הַפַּ֙עַם֙ יִלָּוֶ֤ה אִישִׁי֙ אֵלַ֔י כִּֽי־יָלַ֥דְתִּי ל֖וֹ שְׁלֹשָׁ֣ה בָנִ֑ים עַל־כֵּ֥ן קָרָֽא־שְׁמ֖וֹ לֵוִֽי׃

And she conceived again, and bore a son; and said, Now this time will my husband be joined to me, because I have born him three sons; therefore was his name called Levi.
