Exodus 33:19-23; Exodus 34:1-3

19 He said, "I will cause all My goodness to pass in front of you, and I will proclaim the name Yahweh before you. I will be gracious to whom I will be gracious, and I will have compassion on whom I will have compassion." 20 But He answered, "You cannot see My face, for no one can see Me and live." 21 The Lord said, "Here is a place near Me. You are to stand on the rock, 22 and when My glory passes by, I will put you in the crevice of the rock and cover you with My hand until I have passed by. 23 Then I will take My hand away, and you will see My back, but My face will not be seen."
1 The Lord said to Moses, "Cut two stone tablets like the first ones, and I will write on them the words that were on the first tablets, which you broke. 2 Be prepared by morning. Come up Mount Sinai in the morning and stand before Me on the mountaintop. 3 No one may go up with you; in fact, no one must be seen anywhere on the mountain. Even the flocks and herds are not to graze in front of that mountain."
