Deuteronomy 19:10-12

Darby Translation

¹⁰ that innocent blood be not shed in the midst of thy land which Jehovah thy God giveth thee for an inheritance, and blood come not upon thee.

¹¹ But if a man hate his neighbour, and lie in wait for him, and rise up against him, and smite him mortally that he die, and he flee into one of these cities,

¹² then the elders of his city shall send and fetch him thence, and deliver him into the hand of the avenger of blood, that he may die.
