Exodus 33:20-23 New International Version (NIV)

20. But,” he said, “you cannot see my face, for no one may see me and live.”

21. Then the Lord said, “There is a place near me where you may stand on a rock.

22. When 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.

23. Then I will remove my hand and you will see my back; but my face must not be seen.”
