Kabbalah Mazmur 78:23: Sha'arei Orah

The explanation is as follows: HaShem-יהו״ה, blessed is He, “Rides upon the heavens with your help,” and as your reward for having glorified Him by your hand, He affixes the Shechakim-שחקים to draw all blessings down from His Supernal treasuries. This is as stated,¹⁰⁰Isaiah 45:8 “O’ heavens, pour forth from above and let the Shechakim-שחקים drip righteousness-Tzeddek-צדק; let the earth-Eretz-ארץ open up for salvation and righteousness-Tzeddakah-צדקה to flourish.” Similarly, another verse states,¹⁰¹Job 36:28 “So that the Shechakim-שחקים may drip, pouring out over a multitude of people,” and likewise,¹⁰²Psalms 78:23 “He has commanded the Shechakim-שחקים above and opened the doors of the heavens.”

Thus, from the heavens-Shamayim-שמים influence descends to the Shechakim-שחקים, and from the Shechakim-שחקים to the Living God-E”l Chai-א״ל חי, and from the Living God-E”l Chai-א״ל חי to the Lord-Adona”y-אדנ״י. This whole mystery is contained in the verse,¹¹³Isaiah 45:8 “Pour out, O’ heavens, from above, and let the Shechakim-שחקים drip righteousness-Tzeddek-צדק.” Similarly, it states,¹¹⁴Psalms 78:23 “He has commanded the Shechakim-שחקים from above, and opened the doors of the heavens.” The explanation of this verse is as follows: In the words, “He has commanded the Shechakim-שחקים from above,” the word “Mima’al-ממעל” means “from above,” referring to what is above them. What is above them? The heavens-Shamayim-שמים, as it states, “and opened the doors of the heavens-Shamayim-שמים.”
