Exodus 24:6-8

24:6 Moses took half of the blood and put it in bowls, and half of the blood he splashed on the altar. 24:7 He took the Book of the Covenant and read it aloud to the people, and they said, “We are willing to do and obey all that the Lord has spoken.” 24:8 So Moses took the blood and splashed it on the people and said, “This is the blood of the covenant that the Lord has made with you in accordance with all these words.”
