Exodus 33:18-23

And he said: Shew me thy glory. He answered: I will shew thee all good, and I will proclaim in the name of the Lord before thee: And I will have mercy on whom I will, and I will be merciful to whom it shall please me. And again he said: Thou canst not see my face: for man shall not see me and live. And again he said: Behold, there is a place with me, and thou shalt stand upon the rock. And when my glory shall pass, I will set thee in a hole of the rock, and protect thee with my right hand, till I pass. And I will take away my hand, and thou shalt see my back parts: but my face thou canst not see.
