Deuteronomy 12:21-23

New Revised Standard Version, Anglicised Catholic Edition

²¹ If the place where the Lord your God will choose to put his name is too far from you, and you slaughter as I have commanded you any of your herd or flock that the Lord has given you, then you may eat within your towns whenever you desire. ²² Indeed, just as gazelle or deer is eaten, so you may eat it; the unclean and the clean alike may eat it. ²³ Only be sure that you do not eat the blood; for the blood is the life, and you shall not eat the life with the meat.
