Deuteronomy 19:9

10 and innocent blood is not shed in the midst of thy land which Jehovah thy God is giving to thee -- an inheritance, and there hath been upon thee blood.
11 `And when a man is hating his neighbour, and hath lain in wait for him, and risen against him, and smitten him -- the life, and he hath died, and he hath fled unto one of these cities,
