Exodus 24:3-8

So Moses went to the people and told them everything GOD had said—all the rules and regulations. They all answered in unison: “Everything GOD said, we’ll do.” Then Moses wrote it all down, everything GOD had said. He got up early the next morning and built an Altar at the foot of the mountain using twelve pillar-stones for the twelve tribes of Israel. Then he directed young Israelite men to offer Whole-Burnt-Offerings and sacrifice Peace-Offerings of bulls. Moses took half the blood and put it in bowls; the other half he threw against the Altar. Then he took the Book of the Covenant and read it as the people listened. They said, “Everything GOD said, we’ll do. Yes, we’ll obey.” Moses took the rest of the blood and threw it out over the people, saying, “This is the blood of the covenant which GOD has made with you out of all these words I have spoken.” * * *
