Hebrews 9:18-21 That is why even the first covenant was not put into effect without blood.

MSB⁽ⁱ⁾ ¹⁸ That is why even the first covenant was not put into effect without blood. ¹⁹ For when Moses had proclaimed every commandment of the law to all the people, he took the blood of calves and goats, along with water, scarlet wool, and hyssop, and sprinkled the scroll and all the people, ²⁰ saying, “This is the blood of the covenant, which God has commanded you to keep.” ²¹ In the same way, he sprinkled with blood the tabernacle and all the vessels used in worship.
