Deuteronomy 21

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.

Chapter 21 In this chapter provision is made, I. For the putting away of the guilt of blood from the land, when he that shed it had fled from justice (v. 1-9). II. For the preserving of the honour of a captive maid (v. 10–14). III. For the securing of the right of a first-born son, though he were not a favourite (v. 15–17). IV. For the restraining and punishing of a rebellious son (v. 18–21). V. For the maintaining of the honour of human bodies, which must not be hanged in chains, but decently buried, even the bodies of the worst malefactors (v. 22, 23).Verses 1-9 Care had been taken by some preceding laws for the vigorous and effectual persecution of a wilful murderer (ch. 19:11 etc.), the putting of whom to death was the putting away of the guilt of blood from the land; but if this could not be done, the murderer not being discovered, they must not think that the land was in no danger of contracting any pollution because it was not through any neglect of theirs that the murderer was unpunished; no, a great solemnity is here provided for the putting away of the guilt, as an expression of their dread and detestation of that sin.I. The case supposed is that one is found slain, and it is not known who slew him, v. 1. The providence of God has sometimes wonderfully brought to light these hidden works of darkness, and by strange occurrences the sin of the guilty has found them out, insomuch that it has become a proverb, Murder will out. But it is not always so; now and then the devil’s promises of secresy and impunity in this world are made good; yet it is but for a while: there is a time coming when secret murders will be discovered; the earth shall disclose her blood (Isa. 26:21), upon the inquisition which justice makes for it; and there is an eternity coming when those that escaped punishment from men will lie under the righteous judgment of God. And the impunity with which so many murders and other wickednesses are committed in this world makes it necessary that there should be a day of judgment, to require that which is past, Eccl. 3:15.II. Directions are given concerning what is to be done in this case. Observe,1. It is taken for granted that a diligent search had been made for the murderer, witnesses examined, and circumstances strictly enquired into, that if possible they might find out the guilty person; but if, after all, they could not trace it out, not fasten the charge upon any, then, (1.) The elders of the next city (that had a court of three and twenty in it) were to concern themselves about this matter. If it were doubtful which city was next, the great sanhedrim were to send commissioners to determine that matter by an exact measure, v. 2, 3. Note, Public persons must be solicitous about the public good; and those that are in power and reputation in cities must lay out themselves to redress grievances, and reform what is amiss in the country and neighbourhood that lie about them. Those that are next to them should have the largest share of their good influence, as ministers of God for good. (2.) The priests and Levites must assist and preside in this solemnity (v. 5), that they might direct the management of it in all points according to the law, and particularly might be the people’s mouth to God in the prayer that was to be put up on this sad occasion, v. 8. God being Israel’s King, his ministers must be their magistrates, and by their word, as the mouth of the court and learned in the laws, every controversy must be tried. It was Israel’s privilege that they had such guides, overseers, and rulers, and their duty to make use of them upon all occasions, especially in sacred things, as this was. (3.) They were to bring a heifer down into a rough and unoccupied valley, and to kill it there, v. 3, 4. This was not a sacrifice (for it was not brought to the altar), but a solemn protestation that thus they would put the murderer to death if they had him in their hands. The heifer must be one that had not drawn in the yoke, to signify (say some) that the murderer was a son of Belial; it must be brought into a rough valley, to signify the horror of the fact, and that the defilement which blood brings upon a land turns it into barrenness. And the Jews say that unless, after this, the murderer was found out, this valley where the heifer was killed was never to be tilled nor sown. (4.) The elders were to wash their hands in water over the heifer that was killed, and to profess, not only that they had not shed this innocent blood themselves, but that they knew not who had (v. 6, 7), nor had knowingly concealed the murderer, helped him to make his escape, or been any way aiding or abetting. To this custom David alludes, Ps. 26:6, I will wash my hands in innocency; but if Pilate had any eye to it (Mt. 27:24) he wretchedly misapplied it when he condemned Christ, knowing him to be innocent, and yet acquitted himself from the guilt of innocent blood.
