Exodus 33:20-23 King James Version (KJV)
20 And he said, Thou canst not see my face: for there shall no man see me, and live.
21 And the Lord said, Behold, there is a place by me, and thou shalt stand upon a rock:
22 And it shall come to pass, while my glory passeth by, that I will put thee in a clift of the rock, and will cover thee with my hand while I pass by:
23 And I will take away mine hand, and thou shalt see my back parts: but my face shall not be seen.
