Deuteronomy 12:23-25
23
Only be sure that you don't eat the blood: for the blood is the life; and you shall not eat the life with the flesh.
24
You shall not eat it; you shall pour it out on the earth as water.
25
You shall not eat it; that it may go well with you, and with your children after you, when you shall do that which is right in the eyes of Yahweh.
