King James Version

⁵ And he sent young men of the children of Israel, which offered burnt offerings, and sacrificed peace offerings of oxen unto the Lord.

⁶ And Moses took half of the blood, and put it in basons; 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 the Lord hath said will we do, and be obedient.
