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.Eared - i. e., plowed; compare Genesis 45:6 note and references. The word is derived from the Latin, and is in frequent use by English writers of the fifteenth and two following centuries.

Strike off the heifer's neck - Rather, "break its neck" (compare Exodus 13:13). The mode of killing the victim distinguishes this lustration from the sin-offering, in which there would be of course shedding and sprinkling of the blood.

CHAPTER 21

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.

In testimony of their innocency. See Poole "Matthew 27:24".

And all the elders of that city that are next unto the slain man,.... The whole court of judicature belonging to it, all the magistracy of it; even though there were an hundred of them, Maimonides (x) says:

shall wash their hands over the heifer that is beheaded in the valley: in token of their innocence, and this they did not only for themselves, but for the whole city, being the representatives of it; see Psalm 26:6. Some think that this is a confirmation of the sense embraced by some, that it was a strong stream to which the heifer was brought; and there might be a stream of water here, and a valley also; though it would be no great difficulty to get from the city, which was near, a sufficient quantity of water to wash the hands of the elders with. This may denote the purification of sin by the blood of Christ, when it is confessed over him; and shows that priests and elders, ministers of the word, as well as others, stand in need of it; and that even those concerned in the death of Christ shared in the benefits of it.

And all the elders of that city, that are next unto the slain man, shall wash their hands over the heifer that is beheaded in the valley:
