Deuteronomy 12:16-23

16but you must not eat the blood; pour it on the ground like water.

17Within your gates you must not eat the tithe of your grain or new wine or oil, the firstborn of your herds or flocks, any of the offerings that you have vowed to give, or your freewill offerings or special gifts. 18Instead, you must eat them in the presence of the LORD your God at the place the LORD your God will choose—you, your sons and daughters, your menservants and maidservants, and the Levite within your gates. Rejoice before the LORD your God in all you do, 19and be careful not to neglect the Levites as long as you live in your land.

20When the LORD your God expands your territory as He has promised, and you crave meat and say, “I want to eat meat,” you may eat it whenever you want. 21If the place where the LORD your God chooses to put His Name is too far from you, then you may slaughter any of the herd or flock He has given you, as I have commanded you, and you may eat it within your gates whenever you want. 22Indeed, you may eat it as you would eat a gazelle or deer; both the ceremonially unclean and the clean may eat it. 23Only be sure not to eat the blood, because the blood is the life, and you must not eat the life with the meat.
