Exodus 33:18-23

Moses said, "Show me your glory, I pray."  And he said, "I will make all my goodness pass before you, and will proclaim before you the name, 'The LORD'; and I will be gracious to whom I will be gracious, and will show mercy on whom I will show mercy.  But," he said, "you cannot see my face; for no one shall see me and live."  And the LORD continued, "See, there is a place by me where you shall stand on the rock;  and while my glory passes by I will put you in a cleft of the rock, and I will cover you with my hand until I have passed by;  then I will take away my hand, and you shall see my back; but my face shall not be seen."
