Deuteronomy 12:26-27

26But thy hallowed things which thou hast, and what thou hast vowed, thou shalt take, and come to the place which Jehovah will choose;

27and thou shalt offer thy burnt-offerings, the flesh and the blood, upon the altar of Jehovah thy 1God; and the blood of thy sacrifices shall be poured out upon the altar of Jehovah thy 2God, and the flesh shalt thou eat.
