Genesis 9:4-6

However, you must not eat meat with its lifeblood still in it, for its life is in the blood. If anyone takes another person’s life, I will demand an account—whether from man or beast, I will demand an account for taking a human life. “Whoever sheds human blood, by other humans he must have his own blood shed; for to kill a person is to kill one made in God’s own beautiful image.
