Hebrews 9:19-22

19For when Moses had spoken every command to all the people according to the law, 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,

20and said, “This is the blood of the covenant that God has commanded you to keep.”

21And both the tabernacle and all the utensils of worship he likewise sprinkled with blood.

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