Exodus 33:17-20

17And Jehovah said to Moses, I will do this thing also that thou hast said; for thou hast found grace in mine eyes, and I know thee by name.

18And he said, Let me, I pray thee, see thy glory.

19And 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.

20And he said, Thou canst not see my face; for Man shall not see me, and live.
