4 Moses wrote down all the Lord's commands. Early the next morning he built an altar at the foot of the mountain and set up twelve stones, one for each of the twelve tribes of Israel.
5 Then he sent young men, and they burnt sacrifices to the Lord and sacrificed some cattle as fellowship offerings.
6 Moses took half the blood of the animals and put it in bowls; and the other half he threw against the altar.
7 Then he took the book of the covenant, in which the Lord's commands were written, and read it aloud to the people. They said, “We will obey the Lord and do everything that he has commanded.”
8 Then Moses took the blood in the bowls and threw it on the people. He said, “This is the blood that seals the covenant which the Lord made with you when he gave all these commands.”
9 Moses, Aaron, Nadab, Abihu, and seventy of the leaders of Israel went up the mountain
10 and they saw the God of Israel. Beneath his feet was what looked like a pavement of sapphire, as blue as the sky.
