Exodus 33:20-23
33:20 But he added, “You cannot see my face, for no one can see me and live.”
33:21 The Lord said, “Here is a place by me; you will station yourself on a rock.
33:22 When my glory passes by, I will put you in a cleft in the rock and will cover you with my hand while I pass by.
33:23 Then I will take away my hand, and you will see my back, but my face must not be seen.”
