God calls Moses, Aaron, Nadab, Abihu and seventy elders of Israel to worship from a distance, and only Moses is to come near to the Lord. Moses tells the people all the Lord's words and laws, and the people answer with one voice that they will do everything the Lord has said. Moses writes the words down, rises early and builds an altar at the foot of the mountain with twelve pillars for the twelve tribes.
Young men of Israel offer burnt offerings and peace offerings. Moses takes half of the blood and puts it in basins, and the other half he throws against the altar. He reads the book of the covenant aloud, and the people again promise to obey. Then Moses sprinkles the blood on the people and declares that it is the blood of the covenant the Lord has made with them.
Moses, Aaron, Nadab, Abihu and the seventy elders go up and see the God of Israel; under his feet was something like a pavement of sapphire, and God did not lay his hand on them. They eat and drink. Afterward the Lord calls Moses up the mountain to receive the tablets of stone. Moses goes up with Joshua and leaves Aaron and Hur in charge. The cloud covers the mountain for six days, on the seventh God calls to Moses from the cloud, and the glory of the Lord looks like a consuming fire. Moses enters the cloud and stays forty days and forty nights.
