Hebrews 9:18-22

Therefore even the first covenant was not inaugurated without blood. For when every commandment had been spoken by Moses to all the people according to the Law, he took the blood of the calves and the goats, with water and scarlet wool and hyssop, and sprinkled both the book itself and all the people, saying, “THIS IS THE BLOOD OF THE COVENANT WHICH GOD COMMANDED YOU.” And in the same way he sprinkled both the tabernacle and all the vessels of the ministry with the blood. And according to the Law, one may almost say, all things are cleansed with blood, and without shedding of blood there is no forgiveness.
