Deuteronomy 12:15-16

15But you may kill your animals and eat the meat in any of the towns where you live. When the Lord your God blesses you and he gives you animals, you may eat them as often as you want. It is the same as if you are eating meat from deer. Anyone may eat it. That includes people who are clean and people who are unclean.

16But you must not eat the blood of any animal. You must pour it on the ground like water.
