Deuteronomy 12:25-27

25thou shalt not eat it; that it may go well with thee, and with thy children after thee, when thou shalt do what is right in the eyes of Jehovah.

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.
