Settlement for an Unknown Murderer's Crime

211 If someone is found slain, lying in a field in the land the Lord your God is giving you to possess, and it is not known who the killer was, 2 your elders and judges shall go out and measure the distance from the body to the neighboring towns. 3 Then the elders of the town nearest the body shall take a heifer that has never been worked and has never worn a yoke 4 and lead it down to a valley that has not been plowed or planted and where there is a flowing stream. There in the valley they are to break the heifer's neck. 5 The Levitical priests shall step forward, for the Lord your God has chosen them to minister and to pronounce blessings in the name of the Lord and to decide all cases of dispute and assault. 6 Then all the elders of the town nearest the body shall wash their hands over the heifer whose neck was broken in the valley, 7 and they shall declare: "Our hands did not shed this blood, nor did our eyes see it done. 8 Accept 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, 9 and 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.

Commentary on Deuteronomy 21:1-9

(Read Deuteronomy 21:1-9)

If a murderer could not be found out, great solemnity is provided for putting away the guilt from the land, as an expression of dread and detesting of that sin. The providence of God has often wonderfully brought to light these hidden works of darkness, and the sin of the guilty has often strangely found them out. The dread of murder should be deeply impressed upon every heart, and all should join in detecting and punishing those who are guilty. The elders were to profess that they had not been any way aiding or abetting the sin. The priests were to pray to God for the country and nation, that God would be merciful. We must empty that measure by our prayers, which others are filling by their sins. All would be taught by this solemnity, to use the utmost care and diligence to prevent, discover, and punish murder. We may all learn from hence to take heed of partaking in other men's sins. And we have fellowship with the unfruitful works of darkness, if we do not reprove them.
