Hebrews 9:18-20

18So even the first covenant was not put in force without [the shedding of] blood.

19For 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,

20saying, “This is the blood of the covenant [that seals and ratifies the agreement] which God ordained and commanded [me to deliver to] you.”
