Kabbalah к Йешайау 63:7

Rabbi Elazar said, "O, how great is Your goodness, which You have laid up for those who fear You" (Ps. 31:20). How great is the heavenly abundance that the Holy One, blessed be He, shall bestow on human beings; to those sin-fearing, divine, and righteous men who learn the Torah as they arrive at the World to Come. It is not only written, "Your goodness," but also "how great is Your goodness." And who is He? "The memory of Your goodness" (Ps. 145:7), which is the pleasure of life that is drawn from the World to Come down to the life of the Worlds. This is"the memory of your goodness," which is certainly "the great goodness toward the house of Yisrael" (Isaiah 63:7).
