Exodus 33:21-23

21 And the LORD said, Behold, there is a place by me, and you shall stand on a rock:

22 And it shall come to pass, while my glory passes by, that I will put you in a cleft of the rock, and will cover you with my hand while I pass by:

23 And I will take away my hand, and you shall see my back parts: but my face shall not be seen.
