Sohar, Bereshit 33

1R. Eleazar came forward first and expounded the verse: The voice of the Lord is upon the waters: the God of glory thundereth, even the Lord upon many waters (Ps. 29, 3). He said, ‘“The voice of the Lord” is the supernal voice presiding over the waters, which flow from grade to grade until they are all collected in one place and form one gathering. It is this voice which sends them forth each in its course, like a gardener who conducts water through various channels to the requisite spots.

2“The God of glory thundereth”: this is the side that issues from Geburah (Force), as it is written, “Who can understand the thunder of his mighty deeds (geburotov)?” (Job. 26, 14). “The Lord upon many waters”: this is the supernal Wisdom, which is called Yod, and which is “upon the many waters”, the secret source that issues therefrom.’
