Deuteronomy 12:20-28 - The Sanctity Of Blood
20 When the LORD your God enlarges your territory just as he told you and you say "I want to eat meat' since you desire to eat it, you may do so as much as you please. 21 "If the place where the LORD your God chooses to establish his name is distant from you, then you may slaughter from your herd and your flock what the LORD has provided for you, as he instructed you. You may consume them in your cities as much as you please. 22 You may eat them, just as you would gazelle and deer. Ritually unqualified and qualified people may eat them. 23 Only be sure to refrain from eating blood, because blood is the source of life and you must not consume blood with the meat. 24 You must not consume it; instead, pour it on the ground as you would water. 25 You must not eat it, so that life will go well for you and for your children after you. Then you'll do what is right in the eyes of the LORD.
26 "You may carry and bring only your consecrated gifts and offerings in fulfillment of promises to the place that the LORD will choose. 27 You must offer your burnt offerings, both the meat and the blood, on the altar of the LORD your God. You must offer the blood by pouring it on the altar of the LORD your God while you consume the meat. 28 Be sure to observe all these words that I'm commanding you, in order that life may go well for you and your children after you forever, for this is good and right in the eyes of the LORD your God."
