Exodus 24:5-7

American Standard Version

⁵ And he sent young men of the children of Israel, who offered burnt-offerings, and sacrificed peace-offerings of oxen unto Jehovah. ⁶ And Moses took half of the blood, and put it in basins; and half of the blood he sprinkled on the altar. ⁷ And he took the book of the covenant, and read in the audience of the people: and they said, All that Jehovah hath spoken will we do, and be obedient.
