Hebrews 9:18-22

That is why even the first covenant was put into effect with the blood of an animal. For after Moses had read each of God’s commandments to all the people, he took the blood of calves and goats, along with water, and sprinkled both the book of God’s law and all the people, using hyssop branches and scarlet wool. Then he said, “This blood confirms the covenant God has made with you.” And in the same way, he sprinkled blood on the Tabernacle and on everything used for worship. In fact, according to the law of Moses, nearly everything was purified with blood. For without the shedding of blood, there is no forgiveness.
