Leviticus 17:10, 14

“Anyone from the house of Israel or from the aliens who reside among them who eats any blood,  I will turn  against that person who eats blood and cut him off from his people.

Since the life of every creature is its blood, I have told the Israelites: You are not to eat the blood of any creature,  because the life of every creature is its blood; whoever eats it must be cut off.
