Hebrews 9:18-21 This is why even the first covenant was not ratified without blood.

Common⁽ⁱ⁾ ¹⁸ This is why even the first covenant was not ratified without blood. ¹⁹ For when every commandment of the law had been declared by Moses to all the people, he took the blood of calves and goats, with water and scarlet wool and hyssop, and sprinkled both the book itself and all the people, ²⁰ saying, "This is the blood of the covenant which God has commanded you." ²¹ And in the same way he sprinkled with the blood both the tabernacle and all the vessels used in worship.
