Exodus 33:19-23 (King James Version)

 ¹⁹And he said, I will make all my goodness pass before thee, and I will proclaim the name of the LORD before thee; and will be gracious to whom I will be gracious, and will shew mercy on whom I will shew mercy.

 ²⁰And he said, Thou canst not see my face: for there shall no man see me, and live.

 ²¹And the LORD said, Behold, there is a place by me, and thou shalt stand upon a rock:

 ²²And it shall come to pass, while my glory passeth by, that I will put thee in a clift of the rock, and will cover thee with my hand while I pass by:

 ²³And I will take away mine hand, and thou shalt see my back parts: but my face shall not be seen.
