Deuteronomy 12:20-28 - The Sanctity Of Blood
20 If, when the LORD thy God hath enlarged thy coasts as he hath promised thee, thou say, 'I will eat flesh, because thy soul longeth to eat flesh': then thou shalt eat flesh, whatsoever thy soul lusteth. 21 If the place which the LORD thy God hath chosen to put his name there be too far from thee, then thou mayest kill of thy oxen and of thy sheep which the LORD hath given thee as I have commanded thee, and thou mayest eat in thine own city whatsoever thy soul lusteth. 22 Neverthelater, as the roe and the hart is eaten, even so thou shalt eat it: the unclean and the clean indifferently thou shalt eat. 23 But be strong that thou eat not the blood. For the blood, that is the life: and thou mayest not eat the life with the flesh: 24 thou mayest not eat it, but must pour it upon the earth as water. 25 See thou eat it not, therefore, that it may go well with thee and with thy children after thee, when thou shalt have done that which is right in the sight of the LORD.
26 But thy holy things which thou hast, and thy vows, thou shalt take and go unto the place which the LORD hath chosen, 27 and thou shalt offer thy burnt offerings, both flesh and blood upon the altar of the LORD thy God, and the blood of thine offerings thou shalt pour out upon the altar of the LORD thy God, and shalt eat the flesh. 28 Take heed and hear all these words which I command thee that it may go well with thee and with thy children after thee forever, when thou doest that which is good and right in the sight of the LORD thy God.
