Deuteronomy 21:8-9

JPS_ASV_Byz(i) 8 Forgive, O LORD, Thy people Israel, whom Thou hast redeemed, and suffer not innocent blood to remain in the midst of Thy people Israel.' And the blood shall be forgiven them. 9 So shalt thou put away the innocent blood from the midst of thee, when thou shalt do that which is right in the eyes of the LORD.
