Kabbalah zu Jeschijahu 52:13

He opened the discussion with the verse, "Behold, My servant shall prosper, he shall be exalted and extolled, and be very high" (Isaiah 52:13). Happy is the portion of the righteous, to whom the Holy One, blessed be He, revealed the ways of the Torah, so they may follow them. Come and behold, the verse, "Behold, my servant shall prosper," contains a supernal mystery, which has already been explained. Yet come and behold, when the Holy One, blessed be He, created the universe He made the moon and He decreased her lights in such a way that she had nothing of her own. Because she made herself small, she shone from the sun, by the power of the Supernal Lights.
