Deuteronomy 21:6-8

“The elders of the town must wash their hands over the heifer whose neck was broken. Then they must say, ‘Our hands did not shed this person’s blood, nor did we see it happen. O LORD, forgive your people Israel whom you have redeemed. Do not charge your people with the guilt of murdering an innocent person.’ Then they will be absolved of the guilt of this person’s blood.
