וַיָּ֣סֶךְ בִּדְלָתַ֣יִם יָ֑ם בְּ֝גִיח֗וֹ מֵרֶ֥חֶם יֵצֵֽא׃
און װער האָט פֿאַרצאַמט מיט טירן דעם ים, װען ער האָט אױסגעבראָכן און איז פֿון טראַכט אַרױס?
Akeidat Yitzchak
(7) At the time of creation, the Lord had said that the waters should collect together in one place. He had stipulated at that time that should the need arise, this state of affinity could be suspended. It was a reminder of this agreement that caused the separation of the waters of the sea at that moment. (Shemot Rabbah 21)
