Deuteronomy 12:1, 15, 23 "These are the regulations and the judicial decisions that You should be careful to carry out...whenever your soul craves it...eat meat...only the blood You must not eat. On the earth you should pour it out as water...Simply be firmly resolved not to eat the blood, because the blood is the soul...You must not eat it, in order that it may go well with you and your sons after you...Every word that I am commanding YOU is what YOU should becareful to do. You must not add to it nor take away from it. Deuteronomy 12:32
