Deuteronomy 19:11-13

Young's Literal Translation

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,

¹² then the elders of his city have sent and taken him from thence, and given him into the hand of the redeemer of blood, and he hath died;

¹³ thine eye hath no pity on him, and thou hast put away the innocent blood from Israel, and it is well with thee.
