Deuteronomy 19:11-12

Webster(i) 11 But if any man shall hate his neighbor, and lie in wait for him, and rise up against him, and smite him mortally, that he dieth, and he shall flee into one of these cities: 12 Then the elders of his city shall send and bring him thence, and deliver him into the hand of the avenger of blood, that he may die.
