Hebrews 9:15-20

15Therefore he is the mediator of a new covenant, so that those who are called may receive the promised eternal inheritance, since a death has occurred that redeems them from the transgressions committed under the first covenant. 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.”
