Some think these words were announced lest the people, being terrified by their evils, should become wholly dejected; and they elicit this meaning, -- that God placed this dreadful spectacle of evils before their eyes, that the Jews might prepare and strengthen themselves for enduring them; that though nations should everywhere rise up, they might yet abide arm in the hope, that God would be the defender of his own Church. But the Prophet, I doubt not, continues the same discourse, and denounces war on the heathen nations, who had molested the Church with so many troubles; Publish this, he says, among the nations, proclaim war, rouse the strong; let them come, let them ascend: and we know how necessary it was by such means to confirm what he had previously said: for the ungodly are moved by no threats, nay, they laugh to scorn all God's judgments; while the faithful yielding to their evils, can hardly raise up their minds, even though God promises to be a helper to them. Except, then, the matter had been set forth as painted before their eyes they would not have experienced the power of consolation. Hence the lively representation we see here was intended for this end, -- that the people, being led to view the whole event, might entertain hope of their future salvation, while they now saw God collecting his army, and mustering his forces to punish the enemies of his Church. The faithful, then not only hearing by mere words that this would be, but also seeing, as it were, with their eyes what the Lord sets forth by a figure, and a lively representation, were more effectually impressed and felt more assured that God would become at length their deliverer.

We now then see why the Prophet here bids war to be everywhere announced and proclaimed, and also why he bids the strong to assemble, and all warlike men to ascend; as though he said, "The Lord will not disappoint you with empty words, but will come provided with an army to save you. When ye hear, then, that he will be the author of your salvation, think also that all nations are in his power, and that the whole world can in a moment be roused up by his rod, so that all its forces may from all quarters come together, and all the power of the world meet in obedience to him. Know, then, that being provided with his forces, he comes not to you naked, nor feeds you with mere words, as they are wont to do who have no help to give but words only: this is not what God does; for he can even to-day execute what he has denounced; but he stays for the ripened time. In the meanwhile, give him his honor, and know that there is not wanting the means to protect you, if he wished; but he would have you for a time to be subject to the cross and to tribulations that he may at length avenge the wrongs done to you."

It may be now asked who are the nations meant by the Prophet? for he said before, that God would visit all nations with punishment, whereas, there was then no nation in the world friendly to the Jews. But in this there is nothing inconsistent; for God caused all the enemies of the Church to assail one another on every side, and to destroy themselves with mutual slaughters. Hence, when he designed to take vengeance on the Tyrians and Sidonians, he roused up the Persian and Medes; and when he purposed to punish the Persian and Medes, he called the Greeks into Asia; and he had before brought low the Assyrians. Thus he armed all nations, but each in its turn; and one after the other underwent the punishment they deserved. And so the expression of the Prophet must not be taken in a too restricted sense, as though the Lord would at the same time collect an army from the whole world, to punish the enemies of his Church; but that he rouses the whole world, so that some suffer punishment from others; and yet no enemy of the Church remains unpunished. We now perceive the Prophet's objects in saying, Publish this among the nations; that is, God will move dreadful tumults through the whole world, and will do this for the sake of his Church: for though he exposes his people to many miseries, he will yet have the remnant, as we have before seen, to be saved.

He afterwards adds, Beat your plowshares into swords. When Isaiah and Micah prophesied of the kingdom of Christ, they said, 'Beat your swords into pruninghooks, and your spears into plowshares', (Isaiah 2:4, Micah 4:3.) This sentence is now inverted by Joel. The words of Isaiah and Micah were intended figuratively to show that the world would be at peace when Christ reconciled men to God, and taught them to cultivate brotherly kindness. But the Prophet says here, that there would be turbulent commotions everywhere, so that there would be no use made of the plough or of the pruninghook; husbandmen would cease from their labor, the land would remain waste; for this is the case when a whole country is exposed to violence; no one dares go out, all desert their fields, cultivation is neglected. Hence the Prophet says, 'Turn your plowshares into swords, and your pruninghooks into spears;' that is, field labor will cease, and all will strenuously apply themselves to war. And let the weak say, I am strong, for there will then be no exemption from war. Excuses, we know, availed formerly on the ground of age or disease, when soldiers were collected; and if any one could have pleaded disease, he was dismissed; but the Prophet says, that there will be no exemption then; "God", he says, "will excuse none, he will compel all to become warriors, he will even draw out all the sick from their beds; all will be constrained to put on arms". It hence appears how ardently the Lord loves his Church, since he spares no nations and no people, and exempts none from punishment; for all who have vexed the Church must necessarily receive their recompense. Since then God so severely punishes the enemies of his Church, he thereby gives a singular evidence of his paternal love to us.

At length he concludes, There will Jehovah overthrow thy mighty ones. Though the Prophet uses the singular number, "thy", he no doubt refers to the whole earth; as though he said, "Whatever enemies there may be to my people, I will cut them down, however strong they may be." We now perceive that everything the Prophet has hitherto said has been for this end -- to show, that God takes care of the safety of his Church, even in its heaviest afflictions, and that he will be the avenger of wrongs, after having for a time tried the patience of his people and chastised their faults -- that there will be a turn in the state of things, so that the condition of the Church will be ever more desirable, even under its greatest evils, than of those whom the Lord bears with and indulges, and on whom he does not so quickly take vengeance.
