You shall not murder or You shall not kill is a moral imperative included as one of the Ten Commandments, which, according to the Bible, were inscribed onto two stone tablets by the finger of God. The concept of bloodguilt pervades the Bible and entails punishment for the shedding of innocent blood. Do not pollute the land where you are. Bloodshed pollutes the land, and atonement cannot be made for the land on which blood has been shed, except by the blood of the one who shed it. – Numbers 35:33 (NIV)
