The Lord tells Moses to cut two stone tablets like the first and to go up Mount Sinai early in the morning, alone, so that he may write on them the words that were on the first tablets. Moses does so. The Lord comes down in the cloud and passes before him, proclaiming his name: the Lord, the Lord, a God compassionate and gracious, slow to anger and abounding in steadfast love and faithfulness, keeping steadfast love for thousands, forgiving iniquity, transgression and sin, but who will by no means clear the guilty.
Moses bows down and worships, and begs that the Lord go in their midst, though they are a stiff-necked people, and that he pardon their sin. God answers with a covenant promise: he will do wonders such as have not been done in any nation and will drive out the peoples of Canaan. He warns Israel not to make a covenant with them, to tear down their altars and not to worship other gods, because the Lord is jealous. The commands are repeated: make no gods of cast metal, keep the Feast of Unleavened Bread, consecrate the firstborn, rest on the seventh day, celebrate the Feasts of Weeks and Ingathering, and do not boil a young goat in its mother's milk.
Moses stays forty days and forty nights with the Lord without eating bread or drinking water; there the words of the covenant, the ten commandments, are written on the tablets. When he comes down his face shines because he had spoken with God, and Aaron and the people are afraid to come near. Moses calls them, relays what God commanded him and puts a veil over his face, which he removes when he goes in to speak with the Lord.
