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 longeth to eat flesh; thou mayest eat flesh, whatever thy soul desireth. 21If the place which the LORD thy God hath chosen to put his name there shall 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 in thy gates whatever thy soul desireth. 22Even as the roebuck and the hart is eaten, so thou shalt eat them: the unclean and the clean shall eat of them alike.
