Exodus 33:18-23

And he said, Show me, I pray thee, thy glory. And he said, I will make all my goodness pass before thee, and will proclaim the name of Jehovah before thee; and I will be gracious to whom I will be gracious, and will show mercy on whom I will show mercy. And he said, Thou canst not see my face; for man shall not see me and live. And Jehovah said, Behold, there is a place by me, and thou shalt stand upon the rock: and it shall come to pass, while my glory passeth by, that I will put thee in a cleft of the rock, and will cover thee with my hand until I have passed by: and I will take away my hand, and thou shalt see my back; but my face shall not be seen.
