Leviticus 17:13-14

"When someone from the community of Isra'el or one of the foreigners living with you hunts and catches game, whether animal or bird that may be eaten, he is to pour out its blood and cover it with earth.

For the life of every creature - its blood is its life. Therefore I said to the people of Isra'el, 'You are not to eat the blood of any creature, because the life of every creature is its blood. Whoever eats it will be cut off.'
