John Calvin's Bible Commentary
Numbers 31:1
1.And the Lord spake unto Moses. Amongst the other prerogatives which God conferred upon His Church, this one is celebrated, that He armed the godly “to execute vengeance upon the heathen, — to execute upon them the judgment that is written,” (Psalms 149:7) and although the Spirit declares that this should happen under the kingdom of Christ, still He refers to ancient examples, one of which, well worthy of remembrance, is here recorded. The Midianites had organized a wicked conspiracy for the destruction of God’s people: and God, in undertaking to punish this cruel act of theirs, gave a striking proof of His paternal favor towards the Israelites; whilst this grace is doubled by His constituting them the ministers of his judgment. This passage, therefore, shews us how anxious God was for the welfare of His elect people, when He so set Himself against their enemies, as if He would make common cause in all respects with them. At the same time we must observe this additional favor towards them, that although the Israelites themselves were not without blame, He still deigned to appoint them as judges of the Midianites. Inasmuch, however, as He everywhere prohibits His people from indulging the lust of vengeance, we must not forget the distinction between men’s vengeance and His own. He would have His servants, by patiently bearing injuries, overcome evil with good; while, at the same time, He by no means abdicates His own power, but still reserves to Himself the right of inflicting punishment. Nay, Paul, desiring to exhort believers to long-suffering, recalls them to the principle, that God takes upon Himself the office of avenging. (203) Since, then, God is at liberty to execute vengeance, not only by Himself, but also by His ministers, as we have already seen, these two things are not inconsistent with each other, that the passions of the godly are laid under restraint by the Word, that they should not, when injured, seek for vengeance, or retaliate the evils they have received, and still that they are the just and legitimate executioners of God’s vengeance, when the sword is put into their hands. It remains, that whosoever is called to this office, should punish crime with honest zeal, as the minister of God, and not as acting in his own private cause. God here intrusted the office of vengeance upon His people, but by no means in order that they might indulge the lust of their nature: for their feeling ought to have been this, that they should have been ready to pardon the Midianites, (204) and still that they should heartily bestir themselves to inflict punishment upon them.
That, whilst God so severely judged the Midianites, he spared the Moabites, was for the sake of Lot, who was the founder of their race. But I have already frequently reminded my readers that, when God’s judgments surpass our understanding, we should, in sober humility, give glory to His secret, and to us incomprehensible, wisdom: for those who, in this respect, seek to know more than is fitting, elevate themselves too high, in order to plunge with head-long audacity into a profound abyss, in which, at length, all their senses must be overwhelmed. Why was He not at liberty to remit the punishment of the Moabites, and at the same time to repay to the Midianites the recompense which was their due? Besides, it was only for a time that he pardoned the Moabites, until their obstinacy should render them inexcusable, after they had not only abused his forbearance, but tyrannically afflicted their brethren, by whom they had been treated with kindness.
Moreover, God desired, whilst Moses was still alive, again to testify by this final act His love towards His people, in order that they might more cheerfully advance to the possession of the promised land: for this was no feeble encouragement, when they saw that God spontaneously put Himself forward to avenge them. At the same time it was expedient for Moses that, at the very moment of his death, he should feel, by a fresh instance, what care God took for the welfare of the people. For he was able joyfully to leave them in God’s keeping, whose hand he had so recently seen put forth to fulfill to the utmost His gracious purposes towards them. To the same effect were the words, “Thou shalt be gathered unto thy people,” which were undoubtedly spoken as a consolation in death. It was also a reason for making haste; for if the dearth of the holy Prophet had been waited for, perhaps the Israelites would not have dared to attack, with arms in their hands, a peaceful nation, from whom there was no peril or inconvenience impending. But so great was the authority of Moses over them, that they were more ready to obey his bidding than that of any other person.
Although it is said indifferently of the reprobate as well as believers, that they are gathered or congregated to their fathers by death, still this expression shews that men are born for immortality; for it would not be appropriate to say this of the brute animals, whose death is their final destruction, inasmuch as they are without the hope of another life.
