Leviticus 17:12, 14
New International Version 1984 (NIV1984)
12Therefore I say to the Israelites, “None of you may eat blood, nor may an alien living among you eat blood.”
14 because the life of every creature is its blood. That is why I have said to the Israelites, “You must not eat the blood of any creature, because the life of every creature is its blood; anyone who eats it must be cut off.”
