Deuteronomy 12:20-23

“When the LORD your God enlarges your territory, as he has promised you, and you say, ‘I will eat meat,’ because you crave meat, you may eat meat whenever you desire. If the place that the LORD your God will choose to put his name there is too far from you, then you may kill any of your herd or your flock, which the LORD has given you, as I have commanded you, and you may eat within your towns whenever you desire. Just as the gazelle or the deer is eaten, so you may eat of it. The unclean and the clean alike may eat of it. 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 flesh.
