Deuteronomy 12:20-22

20When Jehovah thy God shall enlarge thy border, as he hath promised thee, and thou shalt say, I will eat flesh, because thy soul desireth to eat flesh; thou mayest eat flesh, after all the desire of thy soul. 21If the place which Jehovah thy God shall choose, to put his name there, be too far from thee, then thou shalt kill of thy herd and of thy flock, which Jehovah hath given thee, as I have commanded thee; and thou mayest eat within thy gates, after all the desire of thy soul. 22Even as the gazelle and as the hart is eaten, so thou shalt eat thereof: the unclean and the clean may eat thereof alike.
