8:21ח׳:כ״א
1 א

מנעריו. מנעריו כְּתִיב, מִשֶּׁנִּנְעַר לָצֵאת מִמְּעֵי אִמּוֹ נִתַּן בּוֹ יֵצֶר הָרָע:

. מנעריו FROM HIS YOUTH — This word is written without a Vav after the ע so that it may be read as מנעריו which would imply that from the moment the embryo bestirs itself to have an independent existence the evil inclination is given to it (Genesis Rabbah 34:10).

לא אסף ולא אסף. כָּפַל הַדָּבָר לִשְׁבוּעָה; הוּא שֶׁכָּתוּב אֲשֶׁר נִשְׁבַּעְתִּי מֵעֲבֹר מֵי נֹחַ, וְלֹא מָצִינוּ בָהּ שְׁבוּעָה, אֶלָּא זוֹ שֶׁכָּפַל דְּבָרָיו וְהִיא שְׁבוּעָה וְכֵן דָּרְשׁוּ חֲכָמִים בְּמס' שְׁבוּעוֹת:

לא אסף… ולא אסף I WILL NEVER AGAIN … NEITHER WILL I EVER AGAIN — He repeated the expression that it might serve as a solemn oath, and it is to this that the text (Isaiah 54:9) refers: “For as I have sworn that the waters of Noah [will never again pass over the earth]”. We, however, do not find any explicit oath regarding this, but this passage in which He repeated these words, which may be regarded as an oath. Thus do our Sages explain in Treatise Shevuot 36a.
