קבלה אויף שמות 3:9

The mystery of this third letter of the Name HaShem-יהו״ה, called Vav-ו, includes six names, corresponding to six Sefirot. These are E”l-א״ל, corresponding to the Sefirah of magnanimity-Gedulah, Elohi”m-אלהי״ם, corresponding to the Sefirah of might-Gevurah, HaShem-יהו״ה, corresponding to the Sefirah of splendor-Tiferet, HaShem of Hosts-HaShem Tzva’ot-יהו״ה צבאו״ת, corresponding to the Sefirah of victory-Netzach, God of Hosts-Elohi”m Tzva’ot-אלהי״ם צבאו״ת, corresponding to the Sefirah of majesty-Hod, and the Living God-E”l Chai-א״ל חי, corresponding to the Sefirah of foundation-Yesod. You thus have learned that the mystery of the Vav-ו of the Name HaShem-יהו״ה includes six holy names of HaShem-יהו״ה, blessed is He.

This also is the secret of the verse,³¹⁹Exodus 3:6; Also see the Amidah prayer. “The God of Avraham-Elohei Avraham- אלה״י אברהם, the God of Yitzchak-Elohei Yitzchak-אלה״י יצחק, and the God of Yaakov-V’Elohei Yaakov-ואלה״י יעקב.” That is, so as not to ascribe greatness to the quality of Yitzchak, the verse does not say “and the God of Yitzchak-V’Elohei Yitzchak-ואלה״י יצחק,” but instead, the quality of Yitzchak is subjugated to the quality of kindness-Chessed of Avraham. This is the meaning of, “The two of them went together.” That is, the quality of Yitzchak does not have the authority to go forth until the quality of Avraham argues for merit, and if this was not so, the quality of Yitzchak would destroy the world.³²⁰See Rashi to Genesis 1:1 and elsewhere. This is the secret of the verse,³²¹Genesis 22:1 “And God-Elohi”m-אלהי״ם tested-Nisah-נסה Avraham,” meaning that the name Elohi”m-אלהי״ם gave its banner-Neis-נס over into the hands of Avraham. You also should know that Avraham bound Yitzchak, so that the quality of Yitzchak would be bound, hand and foot,³²²See Talmud Bavli, Shabbat 54a; Midrash Bereishit Rabba 56 under the dominion of the quality of Avraham.³²³That is, the quality of might-Gevurah and judgment-Din is bound hand and foot and cannot make even the slightest move to act without being granted the authority by the quality of kindness-Chessed of Avraham.
