Exodus 33:20-23

20But,” he said, “you cannot see my face, for no one may see me and live.” 21Then the LORD said, “There is a place near me where you may stand on a rock. 22When my glory passes by, I will put you in a cleft in the rock and cover you with my hand until I have passed by. 23Then I will remove my hand and you will see my back; but my face must not be seen.”
