וְלָכֵ֡ן הִנֵּ֣ה אֲדֹנָי֩ מַעֲלֶ֨ה עֲלֵיהֶ֜ם אֶת־מֵ֣י הַנָּהָ֗ר הָעֲצוּמִים֙ וְהָ֣רַבִּ֔ים אֶת־מֶ֥לֶךְ אַשּׁ֖וּר וְאֶת־כָּל־כְּבוֹד֑וֹ וְעָלָה֙ עַל־כָּל־אֲפִיקָ֔יו וְהָלַ֖ךְ עַל־כָּל־גְּדוֹתָֽיו׃
voici, le Seigneur dirigera contre eux les eaux puissantes et abondantes du Fleuve le roi d’Assyrie avec toutes ses forces; il montera par-dessus son lit et débordera sur toutes ses rives.
Akeidat Yitzchak
The term "water" is used in three different meanings: 1) "water" as we know it, 2) atmosphere, 3) water as something spiritual. Our sages say, "There is no water except Torah” (Baba Kama 17, et al). The statement, "And so it came to be," embraces the coming into existence of these three distinct kinds of water. The absence of the expression ki tov, it was good, is not to be understood negatively, according to whichever reason advanced by the scholars, rather ki tov is used when something existing has been perfected. At that point its goodness becomes manifest. (10) Since during the second day's activities the celestial bodies that were to fill the sky had not been hung yet, the expression "it was good" is obviously not called for. Even if everything had been in place except the sun and the moon, the work would not yet have been completed to call forth the judgment that it had turned out well.
