II. The utter destruction of the Ammonites is threatened. For the reproach cast on the church by her neighbours will be returned into their own bosom, Ps. lxxix. 12. Let us see how terrible the threatening is and the destruction will be. 1. It shall come from the wrath of God, who resents the indignities and injuries done to his people as done to himself (v. 31): I will pour out my indignation as a shower of fire and brimstone upon thee. The least drop of divine indignation and wrath will create tribulation and anguish enough to the soul of man that does evil; what then would a full stream of that indignation and wrath do? "I will blow against thee in the fire of my wrath; that is, I will blow up the fire of my wrath against thee; it shall burn with the utmost vehemence." Thou shalt be for fuel to this fire, v. 32. Note, Wicked men make themselves fuel to the fire of God's wrath; they are consumed by it, and it is inflamed by them. 2. It shall be effected by the sword of war; to them he must cry, as before to Israel, because they had triumphed in Israel's overthrow: The sword, the sword is drawn (v. 28, compare v. 9, 10); it is drawn to consume because of the glittering, because it is brandished and glitters, and is fit to be made use of. God's executions will answer his preparations. This sword, when it is drawn, shall not return into its sheath (v. 30) till it has done the work for which it was drawn. When the sword is drawn it does not return till God causes it to return, and he is in one mind and who can turn him? Who can change his purpose? 3. The persons employed in it are brutish men, and skilful to destroy. Men of such a bad character as this, who have the wit of men to do the work of wild beasts—human reason, which makes them skilful, but no human compassion, which makes them skilful only to destroy—though they are the scandal of mankind, yet sometimes are made use of to serve God's purposes. God delivers the Ammonites into the hands of such, and justly, for they themselves were brutish, and delighted in the destruction of God's Israel. We have reason to pray, as Paul desired to be prayed for, that we may be delivered from wicked and unreasonable men (2 Thess. iii. 2), men that seem made for doing mischief. 4. The place where they should thus be reckoned with: "I will judge thee where thou wast created, where thou wast first formed into a people, and where thou hast been settled ever since, and therefore where thou seemest to have taken root; the land of thy nativity shall be the land of thy destruction." Note, God can bring ruin upon us even where we are most secure, and turn us out of that land which we thought we had a title to not to be disputed and a possession of not to be disturbed. Thy blood shall be shed not only in thy borders, but in the midst of thy land. Lastly, it shall be an irreparable ruin: "Though thou mayest think to recover thyself, it is in vain to think of it; thou shalt be no more remembered with any respect," Ps. ix. 6. Justly is their name blotted out who would have Israel's name for ever lost.
