Deuteronomy 12:20-22

20When Jehovah thy 1God shall enlarge thy border, as he promised thee, and thou say, I will eat flesh, because thy soul longeth to eat flesh, thou mayest eat flesh, according to all the desire of thy soul.

21If the place which Jehovah thy 2God will choose to set his name there be too far from thee, then thou shalt slay of thy kine and of thy sheep which Jehovah hath given thee, as I have commanded thee, and thou shalt eat in thy gates according to all the desire of thy soul.

22Even as the gazelle and the hart is eaten, so thou shalt eat them: the unclean and the clean alike may eat of them.
