Hebrews 9

16 For where a will is involved, the death of the one who made it must be established. 17 For *[Gal. 3:15]a will takes effect only at death, since it is not in force as long as the one who made it is alive. 18 Therefore not even the first covenant was inaugurated *Ex. 24:6,8without blood. 19 For when every commandment of the law had been declared by Moses to all the people, he took *ver. 12the blood of calves and goats, *[Lev. 14:4,7;Num. 19:6,17]with water and scarlet wool and hyssop, and sprinkled both the book itself and all the people, 20 saying, *Cited from Ex. 24:8;[Matt. 26:28]"This is the blood of the covenant that God commanded for you."
