וַיֵּ֤רָא֨וּ ׀ אֲפִ֥יקֵי מַ֗יִם וַֽיִּגָּלוּ֮ מוֹסְד֪וֹת תֵּ֫בֵ֥ל מִגַּעֲרָ֣תְךָ֣ יְהוָ֑ה מִ֝נִּשְׁמַ֗ת ר֣וּחַ אַפֶּֽךָ׃
And the channels of waters appeared, and the foundations of the world were laid bare, at Thy rebuke, O LORD, at the blast of the breath of Thy nostrils.
Rashi on Psalms
the foundations of the world were laid bare for all the waters in the world split.
