Deuteronomy 21:7-9

MLV(i) 7 and they will answer and say, Our hands have not shed this blood, neither have our eyes seen it. 8 Forgive, O Jehovah, your people Israel whom you have redeemed and allow no innocent blood to remain in the midst of your people Israel. And the blood will be forgiven them.
9 So will you put away the innocent blood from the midst of you when you will do what is right in the eyes of Jehovah.
