Deuteronomy 21:1

De 21:1-9. Expiation of Uncertain Murder.

1-6. If one be found slain ... lying in the field, and it be not known who hath slain him--The ceremonies here ordained to be observed on the discovery of a slaughtered corpse show the ideas of sanctity which the Mosaic law sought to associate with human blood, the horror which murder inspired, as well as the fears that were felt lest God should avenge it on the country at large, and the pollution which the land was supposed to contract from the effusion of innocent, unexpiated blood. According to Jewish writers, the Sanhedrin, taking charge of such a case, sent a deputation to examine the neighborhood. They reported to the nearest town to the spot where the body was found. An order was then issued by their supreme authority to the elders or magistrates of that town, to provide the heifer at the civic expense and go through the appointed ceremonial. The engagement of the public authorities in the work of expiation, the purchase of the victim heifer, the conducting it to a "rough valley" which might be at a considerable distance, and which, as the original implies, was a wady, a perennial stream, in the waters of which the polluting blood would be wiped away from the land, and a desert withal, incapable of cultivation; the washing of the hands, which was an ancient act symbolical of innocence--the whole of the ceremonial was calculated to make a deep impression on the Jewish, as well as on the Oriental, mind generally; to stimulate the activity of the magistrates in the discharge of their official duties; to lead to the discovery of the criminal, and the repression of crime.

Introduction

If a man be found slain in a field, and the cause of his death be unknown, the murder shall be expiated by the sacrifice of a heifer in an uncultivated valley, Deu 21:1-4. The rites to be used on the occasion, Deu 21:5-9. The ordinance concerning marriage with a captive, Deu 21:10-14. The law relative to the children of the hated and beloved wives: if the son of the hated wife should be the first-born he shall not be disinherited by the son of the beloved wife, but shall have a double portion of all his father's goods, Deu 21:15-18. The law concerning the stubborn and rebellious son, who, when convicted, is to be stoned to death, Deu 21:19-21. Of the person who is to be hanged, Deu 21:22. His body shall not be left on the tree all night; every one that is hanged on a tree is accursed of God, Deu 21:23.

Verses 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.
