The calamities of the Philistines.
The Philistines had always been enemies to Israel; but the Chaldean army shall overflow their land like a deluge. Those whom God will spoil, must be spoiled. For when the Lord intends to destroy the wicked, he will cut off every helper. So deplorable are the desolations of war, that the blessings of peace are most desirable. But we must submit to His appointments who ordains all in perfect wisdom and justice.
(Read Amos 9:1-10)
The prophet, in vision, saw the Lord standing upon the idolatrous altar at Bethel. Wherever sinners flee from God's justice, it will overtake them. Those whom God brings to heaven by his grace, shall never be cast down; but those who seek to climb thither by vain confidence in themselves, will be cast down and filled with shame. That which makes escape impossible and ruin sure, is, that God will set his eyes upon them for evil, not for good. Wretched must those be on whom the Lord looks for evil, and not for good. The Lord would scatter the Jews, and visit them with calamities, as the corn is shaken in a sieve; but he would save some from among them. The astonishing preservation of the Jews as a distinct people, seems here foretold. If professors make themselves like the world, God will level them with the world. The sinners who thus flatter themselves, shall find that their profession will not protect them.

Commentary on Deuteronomy 2:8-23
(Read Deuteronomy 2:8-23)
We have the origin of the Moabites, Edomites, and Ammonites. Moses also gives an instance older than any of these; the Caphtorims drove the Avims out of their country. These revolutions show what uncertain things wordly possessions are. It was so of old, and ever will be so. Families decline, and from them estates are transferred to families that increase; so little continuance is there in these things. This is recorded to encourage the children of Israel. If the providence of God has done this for Moabites and Ammonites, much more would his promise do it for Israel, his peculiar people. Cautions are given not to meddle with Moabites and Ammonites. Even wicked men must not be wronged. God gives and preserves outward blessings to wicked men; these are not the best things, he has better in store for his own children.
