Tehillim 29:10 Kabbala: Zohar

And this is the secret of the verse, "Hashem sat at the Flood" (Ps. 29:10). What is "sat?" If it had not been written in the scriptures, we could not have said it, (because sat infers) that He sat alone, by Himself and was distinct from the Judgment; here it is written: "Hashem sat," while in another place it is written: "He shall sit alone".
