Exodus 24:6-8 Living Bible (TLB)
6 Moses took half of the blood of these animals and drew it off into basins. The other half he splashed against the altar.
7 And he read to the people the Book he had written—the Book of the Covenant—containing God’s directions and laws. And the people said again, “We solemnly promise to obey every one of these rules.”
8 Then Moses threw the blood from the basins toward the people and said, “This blood confirms and seals the covenant the Lord has made with you in giving you these laws.”
