Exod 33:20-23

20But,” he said, “you cannot see my face; for no one shall see me and live.”21And the Lord continued, “See, there is a place by me where you shall stand on the rock;22and while my glory passes by I will put you in a cleft of the rock, and I will cover you with my hand until I have passed by;23then I will take away my hand, and you shall see my back; but my face shall not be seen.”
