Deuteronomy 21:1-9

“When you are in the land the LORD your God is giving you, someone may be found murdered in a field, and you don’t know who committed the murder. In such a case, your elders and judges must measure the distance from the site of the crime to the nearby towns. When the nearest town has been determined, that town’s elders must select from the herd a heifer that has never been trained or yoked to a plow. They must lead it down to a valley that has not been plowed or planted and that has a stream running through it. There in the valley they must break the heifer’s neck. Then the Levitical priests must step forward, for the LORD your God has chosen them to minister before him and to pronounce blessings in the LORD’s name. They are to decide all legal and criminal cases. “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. By following these instructions, you will do what is right in the LORD’s sight and will cleanse the guilt of murder from your community.
