Hebrews 9:16-22

16For where a will is involved, the death of the one who made it must be established.

17For a will takes effect only at death, since it is not in force as long as the one who made it is alive.

18Therefore not even the first covenant was inaugurated without blood.

19For 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,

20saying, "This is the blood of the covenant that God commanded for you."

21And in the same way he sprinkled with the blood both the tent and all the vessels used in worship.

22Indeed, under the law almost everything is purified with blood, and without the shedding of blood there is no forgiveness of sins.
