Exodus 24:4-7

4So Moses wrote down all the Lord’s words. Early the next morning he built an altar at the foot of the mountain and ⌞set up⌟ 12 sacred stones for the 12 tribes of Israel.

5Then he sent young Israelite men, and they sacrificed bulls as burnt offerings and fellowship offerings to the Lord.

6Moses took half of the blood and put it into bowls, and he threw the other half against the altar.

7Then he took the Book of the Lord’s Promise  and read it while the people listened. They said, “We will obey and do everything the Lord has said.”
