Deuteronomy 19:11-13

MKJV(i) 11 But if a man hates his neighbor and lies in wait for him and rises up against him and strikes his life from him, so that he dies, and flees to one of these cities, 12 then the elders of his city shall send and bring him away from there and deliver him into the hand of the avenger of blood so that he may die. 13 Your eye shall not pity him, but you shall put away innocent blood from Israel, so that it may go well with you.
