Exodus 24:6-8

Young's Literal Translation

⁶ And Moses taketh half of the blood, and putteth in basins, and half of the blood hath he sprinkled on the altar;

⁷ and he taketh the Book of the Covenant, and proclaimeth in the ears of the people, and they say, `All that which Jehovah hath spoken we do, and obey.'

⁸ And Moses taketh the blood, and sprinkleth on the people, and saith, `Lo, the blood of the covenant which Jehovah hath made with you, concerning all these things.'
