Exodus 33:20

17 Yahweh said to Moses, "I will do this thing also that you have spoken; for you have found favor in my sight, and I know you by name."

18 He said, "Please show me your glory."

19 He said, "I will make all my goodness pass before you, and will proclaim the name of Yahweh before you. I will be gracious to whom I will be gracious, and will show mercy on whom I will show mercy."

20 He said, "You cannot see my face, for man may not see me and live."

21 Yahweh also said, "Behold, there is a place by me, and you shall stand on the rock.

22 It will happen, while my glory passes by, that I will put you in a cleft of the rock, and will cover you with my hand until I have passed by;

23 then I will take away my hand, and you will see my back; but my face shall not be seen."
