Exodus 33:18-23

Then Moses said, “I pray that you will let me see you in all your glory.” The LORD answered: All right. I am the LORD, and I show mercy and kindness to anyone I choose. I will let you see my glory and hear my holy name, but I won't let you see my face, because anyone who sees my face will die. There is a rock not far from me. Stand beside it, and before I pass by in all my shining glory, I will put you in a large crack in the rock. I will cover your eyes with my hand until I have passed by. Then I will take my hand away, and you will see my back. You will not see my face.
