Hebrews 9:19

19 It was like this. Moses read God's laws aloud to all the Israelite people. He told them every rule that God had given them. After that, Moses killed some young cows and goats. He took some of their blood and he mixed it with water. He used red wool and some small branches of hyssop to splash the blood and water. He splashed some of the blood onto the book of God's laws. He also splashed some blood onto all the people.
