Exodus 33:18-23

And he said, Let me, I pray thee, see thy glory. And he said, I will make all my goodness pass before thy face, and I will proclaim the name of Jehovah before thee; and I will be gracious to whom I will be gracious, and I will shew mercy on whom I will shew 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: there shalt thou stand on the rock. And it shall come to pass, when 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 me from behind; but my face shall not be seen.
