Exodus 24:4-7

4And aMoses wrote down all the words of the Lord. He rose early in the morning and built an altar at the foot of the mountain, and twelve bpillars, according to the twelve tribes of Israel. 5And he sent young men of the people of Israel, who offered burnt offerings and sacrificed peace offerings of oxen to the Lord. 6And cMoses took half of the blood and put it in basins, and half of the blood he threw against the altar. 7Then he took the Book of the Covenant and read it in the hearing of the people. And they said, dAll that the Lord has spoken we will do, and we will be obedient.”
