Deuteronomy 12:20-22

20When the LORD 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 the LORD 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 the LORD hath given thee, as I have commanded thee, and thou shalt 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 shall eat thereof alike.
