Deuteronomy 12:19-21
19 Take heed to thyself that thou forsake not the Levite as long as thou livest upon the earth.
20 When 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, whatsoever thy soul lusteth after.
21 If the place which the LORD thy God hath chosen 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 in thy gates whatsoever thy soul lusteth after.
