Deuteronomy 21:7-9

Revised Standard Version Catholic Edition

⁷ and they shall testify, ‘Our hands did not shed this blood, neither did our eyes see it shed. ⁸ Forgive, O Lord, thy people Israel, whom thou hast redeemed, and set not the guilt of innocent blood in the midst of thy people Israel; but let the guilt of blood be forgiven them.’ ⁹ So you shall purge the guilt of innocent blood from your midst, when you do what is right in the sight of the Lord.
