17 In other words, a will doesn't go into effect as long as the one who made it is still alive.
18 Blood was also used to put the first agreement into effect.
19 Moses told the people all the Law said they must do. Then he used red wool and a hyssop plant to sprinkle the people and the book of the Law with the blood of bulls and goats and with water.
20 He told the people, “With this blood God makes his agreement with you.”
21 Moses also sprinkled blood on the tent and on everything else used in worship.
22 The Law says that almost everything must be sprinkled with blood, and no sins can be forgiven unless blood is offered.
23 These things are only copies of what is in heaven, and so they had to be made holy by these ceremonies. But the real things in heaven must be made holy by something better.
