Kabbalah su Levitico 13:46

Those who are unholy find that defilement awaits them. Of them, the scripture says, "he is unclean, he shall dwell alone; outside the camp shall his habitation be" (Vayikra 13:46), that is, away from holiness. The impure touches on the impure, as it is written, "and shall cry, unclean, unclean" (Ibid. 45), which means that whoever is unclean cries to the unclean; one seeks out one's own kind.

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".
