5. Concerning the Ammonites, v. 13-15. (1.) See how violently the fire of their anger turned against the people of God; they not only triumphed in their calamities (as we find, Ezek. xxv. 2, 6), but they did themselves use them barbarously; they ripped up the women with child of Gilead, a piece of cruelty the very mention of which strikes a horror upon one's mind; one would think it is not possible that any of the human race should be so inhuman. Hazael was guilty of it, 2 Kings viii. 12. It was done not only in a brutish rage, which falls without consideration upon all that comes before it, but with a devilish design to extirpate the race of Israel by killing not only all that were born, but all that were to be born, worse than Egyptian cruelty. It was that they might enlarge their border, that they might make the land of Gilead their own, and there might be none to lay claim to it or given them any disturbance in the possession of it. We find (Jer. xlix. 1) that the Ammonites inherited Gad (that is, Gilead) under pretence that Israel had no sons, no heirs. We know how heavy the doom of those was, and how heinous their crime, who said, This is the heir; come, let us kill him, and the inheritance shall be ours by occupancy. See what cruelty covetousness is the cause of, and what horrid practices those are often put upon that are greedy to enlarge their own border. (2.) See how violently the fire of God's anger burned against them; shall not God visit for these things done to any of mankind, especially when they are done to his own people? Shall not his soul be avenged on such a nation as this? No doubt, it shall. The fire shall be kindled with shouting in the day of battle, that is, war shall kindle the fire; it shall be a fire accompanied with the sword, or a roaring fire, which shall make a noise like that of soldiers ready to engage, and it shall be as a tempest in the day of the whirlwind, which comes swiftly, furiously, and bears down all before it. Or this tempest and whirlwind shall be as bellows to the fire, to make it burn the stronger, and spread the further. It is particularly threatened that their king and his princes shall go together into captivity, carried away by the king of Babylon, not long after Judah was. See what changes God's providence often makes with men, or rather their own sin; kings become captives, and princes prisoners. Milchom shall go into captivity; some understand it of the god of the Ammonites, whom they called Moloch—a king. He, and his princes, and his priests that attended him, shall to into captivity; their idol shall be so far from protecting them that it shall itself go into captivity with them. Note, Those who by violence and fraud seek to enlarge their own border will justly be expelled and excluded their own border; nor is it strange if those who make no conscience of invading the rights of others be able to make no resistance against those who invade theirs.
