Deuteronomy 19:10-13

AKJV(i) 10 That innocent blood be not shed in your land, which the LORD your God gives you for an inheritance, and so blood be on you. 11 But if any man hate his neighbor, and lie in wait for him, and rise up against him, and smite him mortally that he die, and flees into one of these cities: 12 Then the elders of his city shall send and fetch him there, and deliver him into the hand of the avenger of blood, that he may die. 13 Your eye shall not pity him, but you shall put away the guilt of innocent blood from Israel, that it may go well with you.
