Levítico 17:14

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."

14 For the blood is the life of all flesh: and so I have said to the children of Israel, You may not take any sort of blood as food, and any man who does so will be cut of.
