Kabbalah su Salmi 18:47

Rabbi Elazar opened the discussion with the verse, "Hashem lives; and blessed is my Rock; and let the Elohim (Heb. Elohai) of my salvation be exalted" (Tehilim 18:47). "Elohai" is spelled with a Vav. This verse requires careful study. The phrase, "Hashem lives" refers to the Righteous, the foundation of the world, who is referred to as the life of the worlds. The phrase "and blessed is my Rock" is the meaning of "Blessed be Hashem my Rock" (Tehilim 144:1). The world is sustained by the generosity of the Righteous, "Let the Elohim of my salvation be exalted": "exalted" refers to the upper world, and "Elohai" with a Vav is heaven, as it is written, "The heavens are the heavens of Hashem" (Tehilim 115:16).
