Hebrews 9:18-22

18That is why even the first covenant was inaugurated with blood.

19For when every command had been proclaimed by Moses to all the people according to the law, he took the blood of calves and goats, along with water, scarlet wool, and hyssop, and sprinkled the scroll itself and all the people,

20saying, This is the blood of the covenant that God has ordained for you.

21In the same way, he sprinkled the tabernacle and all the articles of worship with blood.

22According to the law almost everything is purified with blood, and without the shedding of blood there is no forgiveness.
