1 The LORD said to Moses, "Depart; go up from here, you and the people whom you have brought up out of the land of Egypt, to the land of which I swore to Abraham, Isaac, and Jacob, saying, 'To your offspring I will give it.' 2 I will send an angel before you, and I will drive out the Canaanites, the Amorites, the Hittites, the Perizzites, the Hivites, and the Jebusites. 3 Go up to a land flowing with milk and honey; but I will not go up among you, lest I consume you on the way, for you are a stiff-necked people." 4 When the people heard this disastrous word, they mourned, and no one put on his ornaments...

15 And he said to him, "If your presence will not go with me, do not bring us up from here. 16 For how shall it be known that I have found favor in your sight, I and your people? Is it not in your going with us, so that we are distinct, I and your people, from every other people on the face of the earth?" 17 And the LORD said to Moses, "This very thing that you have spoken I will do, for you have found favor in my sight, and I know you by name." 18 Moses said, "Please show me your glory." 19 And he said, "I will make all my goodness pass before you and will proclaim before you my name 'The LORD.' And I will be gracious to whom I will be gracious, and will show mercy on whom I will show mercy. 20 But," he said, "you cannot see my face, for man shall not see me and live." 21 And the LORD said, "Behold, there is a place by me where you shall stand on the rock, 22 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. 23 Then I will take away my hand, and you shall see my back, but my face shall not be seen."

Exodus 33:1-4, 15-23 (ESV)

1 The LORD said to Moses, "Cut for yourself two tablets of stone like the first, and I will write on the tablets the words that were on the first tablets, which you broke. 2 Be ready by the morning, and come up in the morning to Mount Sinai, and present yourself there to me on the top of the mountain...

5 The LORD descended in the cloud and stood with him there, and proclaimed the name of the LORD. 6 The LORD passed before him and proclaimed, "The LORD, the LORD, a God merciful and gracious, slow to anger, and abounding in steadfast love and faithfulness, 7 keeping steadfast love for thousands, forgiving iniquity and transgression and sin, but who will by no means clear the guilty, visiting the iniquity of the fathers on the children and the children's children, to the third and the fourth generation." 8 And Moses quickly bowed his head toward the earth and worshiped. 9 And he said, "If now I have found favor in your sight, O Lord, please let the Lord go in the midst of us, for it is a stiff-necked people, and pardon our iniquity and our sin, and take us for your inheritance."...

29 When Moses came down from Mount Sinai, with the two tablets of the testimony in his hand as he came down from the mountain, Moses did not know that the skin of his face shone because he had been talking with God. 30 Aaron and all the people of Israel saw Moses, and behold, the skin of his face shone, and they were afraid to come near him. 31 But Moses called to them, and Aaron and all the leaders of the congregation returned to him, and Moses talked with them. 32 Afterward all the people of Israel came near, and he commanded them all that the LORD had spoken with him in Mount Sinai. 33 And when Moses had finished speaking with them, he put a veil over his face. 34 Whenever Moses went in before the LORD to speak with him, he would remove the veil, until he came out. And when he came out and told the people of Israel what he was commanded, 35 the people of Israel would see the face of Moses, that the skin of Moses' face was shining. And Moses would put the veil over his face again, until he went in to speak with him.
