Deuteronomy 12:20-28 - The Sanctity Of Blood
20 When Jehovah your God shall make your border larger, as He has promised you, and you shall say, I will eat flesh, because your soul longs to eat flesh; you may eat flesh, whatever your soul desires. 21 If the place which Jehovah your God has chosen to put His name there is too far from you, then you shall kill of your herd and of your flock which Jehovah has given you, as I have commanded you, and you shall eat in your gates whatever your soul desires. 22 Even as the gazelle and the hart is eaten, so you shall eat them. The unclean and the clean shall eat of them alike. 23 Only be sure that you do not eat the blood. For the blood is the life. And you may not eat the life with the flesh. 24 You shall not eat it. You shall pour it on the earth like water. 25 You shall not eat it, so that it may go well with you and with your sons after you, when you shall do what is right in the sight of Jehovah.
26 Only your holy things which you have, and your vows, you shall take and go to the place which Jehovah shall choose. 27 And you shall offer your burnt offerings, the flesh and the blood, on the altar of Jehovah your God. And the blood of your sacrifices shall be poured out on the altar of Jehovah your God, and you shall eat the flesh. 28 Be careful to hear all these words which I command you, so that it may go well with you and with your sons after you forever, when you do the good and right in the sight of Jehovah your God.
