Hebrews 9:18-24

So this is why not even the first covenant was inaugurated without the blood of animals. For Moses ratified the covenant after he gave the people all the commandments of the law. He took the blood of calves and goats, with water, scarlet wool, and a hyssop branch, and sprinkled both the people and the book of the covenant, saying, “This is the blood of the covenant that God commands you to keep.” And later Moses also sprinkled the tabernacle with blood and every utensil and item used in their service of worship. Actually, nearly everything under the law was purified with blood, since forgiveness only comes through an outpouring of blood. And so it was necessary for all the earthly symbols of the heavenly realities to be purified with these animal sacrifices, but the heavenly things themselves required a superior sacrifice than these. For the Messiah did not enter into the earthly tabernacle made by men, which was but an echo of the true sanctuary, but he entered into heaven itself to appear before the face of God in our place.
