Hebrews 9:16-22

For where there is a will and testament involved, the death of the one who made it must be established, for a will and testament takes effect [only] at death, since it is never in force as long as the one who made it is alive. So even the first covenant was not put in force without [the shedding of] blood. For when every commandment in the Law had been read by Moses to all the people, he took the blood of the calves and goats [which had been sacrificed], together with water and scarlet wool and with a bunch of hyssop, and he sprinkled both the scroll itself and all the people, saying, “THIS IS THE BLOOD OF THE COVENANT [that seals and ratifies the agreement] WHICH GOD ORDAINED and COMMANDED [me to deliver to] YOU.” [Ex 24:6-8] And in the same way he sprinkled both the tabernacle and all the containers and sacred utensils of worship with the blood. In fact under the Law almost everything is cleansed with blood, and without the shedding of blood there is no forgiveness [neither release from sin and its guilt, nor cancellation of the merited punishment].
