Deuteronomy 21:7-9

⁷and they shall declare: “Our hands did not shed this blood, nor did our eyes see it done.

⁸Accept this atonement for your people Israel, whom you have redeemed, Lord, and do not hold your people guilty of the blood of an innocent person.” Then the bloodshed will be atoned for,

⁹and you will have purged from yourselves the guilt of shedding innocent blood, since you have done what is right in the eyes of the Lord.
