Isaías 40:17 Cabalá: Zohar & Sha'arei Orah

This is true for a woman who comes from the aspect of the Tree of Knowledge of Good and Evil, but if she is from the Shechinah she remains unchanged. This is the meaning of, "For I am Hashem, I do not change" (Malachi 3:6). "I" is the Shechinah, who has no fear from the other sides [ i.e. the kelipot]. This is the meaning of, "All nations before Him are as nothing" (Isaiah 40:17).

Nor is one to imagine that the “side of impurity” has put the soul in the child: for the impure power only snatched, as it were, at that soul and played with it until it entered into the body of that child. But the impure power visits the child occasionally and longs to possess his body. And after some time the Holy One takes into His own guardianship the soul, and the evil power attains mastery over the body. But eventually body and soul become the possession of the Holy One (in the Resurrection).

If, God forbid, the Jewish people sin, they cause the final Wisdom-Chochmah Acharonah-חכמה אחרונה to separate from Knowledge-Da’at, as in the verse,¹²⁹Proverbs 16:28 “A querulous person estranges the Master-Alooph-אלוף.” Thus, sometimes the final letter Hey-ה separates from the Vav-ו, and the Vav-ו then gathers up above and is unseen, being that His spouse, the lower Hey-ה, has separated from Him. This is the meaning of the verse,¹³⁰Isaiah 40:17 “I shall await HaShem-יהו״ה, who has concealed His face from the House of Yaakov.” That is, since the Indwelling Presence of HaShem-יהו״ה, blessed is He, which is the final letter Hey-ה of the Name HaShem-יהו"ה has separated, therefore the letter Vav-ו is not seen, and Ya”h-י״ה remains alone, in that [it is constant and] there is no separation there. This is the meaning of the verse,¹³¹Isaiah 57:1 “Because of the evil, the righteous-Tzaddik-צדיק is gathered in.” For, with the withdrawal of the letter Vav-ו of the Name HaShem-יהו"ה, which is Splendor-Tiferet, the righteous-Tzaddik-צדיק, which is the lower thorn of the letter Vav-ו, is gathered in.
