Moses said: On the Day of Atonement I will behold the glory of the Holy One, blessed be He, and I will make atonement for the iniquities of Israel. Moses spake before the Holy One, blessed be He: Sovereign of all the universe! "Shew me, I pray thee, thy glory" (Ex. 33:18). The Holy One, blessed be He, said to him: Moses!
Thou art not able to see My glory lest thou die, as it is said, "For men shall not see me and live" (Ex. 33:20); but for the sake of the oath which I have sworn unto thee I will do thy will. Stand at the entrance of || the cave, and I will make all the angels who move before Me pass before thy face. Stand in thy might, and do not fear, as it is said, "And he said, I will make all my goodness pass before thee" (Ex. 33:19).
When thou dost hear the Name which I have spoken to thee, there am I before thee, as it is said, "And he said, I will make all my goodness pass before thee" (ibid.).
