Deuteronomy 12:14-15

but in the place which the LORD shall choose in one of thy tribes, there thou shalt offer thy burnt offerings, and there thou shalt do all that I command thee. Notwithstanding thou mayest kill and eat flesh in all thy gates, whatsoever thy soul lusteth after, according to the blessing of the LORD thy God which he hath given thee: the unclean and the clean may eat thereof, as of the roebuck, and as of the hart.
