Hebrews 9:18-23

18This is why even the first covenant was not put into effect without blood. 19When Moses had proclaimed every command of the law to all the people, he took the blood of calves, together with water, scarlet wool and branches of hyssop, and sprinkled the scroll and all the people. 20He said, “This is the blood of the covenant, which God has commanded you to keep.” Exodus 24:8 21In the same way, he sprinkled with the blood both the tabernacle and everything used in its ceremonies.

22In fact, the law requires that nearly everything be cleansed with blood, and without the shedding of blood there is no forgiveness. 23It was necessary, then, for the copies of the heavenly things to be purified with these sacrifices, but the heavenly things themselves with better sacrifices than these.
