Hebrews 9:18-23 From which we see that neither was the first covenant dedicated without blood.

MKJV⁽ⁱ⁾ ¹⁸ From which we see that neither was the first covenant dedicated without blood. ¹⁹ For when Moses had spoken every precept to all the people according to the Law, he took the blood of calves and of goats, with water and scarlet wool and hyssop, and sprinkled both the book, and all the people, ²⁰ saying, "This is the blood of the covenant which God has enjoined to you." ²¹ And likewise he sprinkled with blood both the tabernacle and all the vessels of the ministry. ²² And almost all things are by the law purged with blood, and without shedding of blood is no remission. ²³ Therefore it was necessary that the patterns of things in the heavens should be purified with these, but the heavenly things themselves were purified with better sacrifices than these.
