Deuteronomy 12:15-16

Notwithstanding, thou mayest kill and eat flesh within all thy gates, after all the desire of thy soul, according to the blessing of Jehovah thy God which he hath given thee: the unclean and the clean may eat thereof, as of the gazelle, and as of the hart. Only ye shall not eat the blood; thou shalt pour it out upon the earth as water.
