Exodus 24:5-8 (King James Version)

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

 ⁶And Moses took half of the blood, and put it in basons; and half of the blood he sprinkled on the altar.

 ⁷And 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.

 ⁸And Moses took the blood, and sprinkled it on the people, and said, Behold the blood of the covenant, which the LORD hath made with you concerning all these words.
