II. Assurance is likewise given of the destruction of the Philistines and their power. This burden, this prophecy, that lay as a load upon them, to sink their state, came in the year that king Ahaz died, which was the first year of Hezekiah's reign, v. 28. When a good king came in the room of a bad one then this acceptable message was sent among them. When we reform, then, and not till then, we may look for good news from heaven. Now here we have, 1. A rebuke to the Philistines for triumphing in the death of king Uzziah. He had been as a serpent to them (v. 29), had bitten them, had smitten them, had brought them very low, 2 Chron. xxvi. 6. He warred against the Philistines, broke down their walls, and built cities among them. But when Uzziah died, or rather abdicated, it was told with joy in Gath and published in the streets of Ashkelon. It is inhuman thus to rejoice in our neighbour's fall. But let them not be secure; for though when Uzziah was dead they made reprisals upon Ahaz, and took many of the cities of Judah (2 Chron. xxviii. 18), yet out of the root of Uzziah should come a cockatrice, a more formidable enemy than Uzziah was, even Hezekiah, the fruit of whose government should be to them a fiery flying serpent, for he should fall upon them with incredible swiftness and fury: we find he did so. 2 Kings xviii. 8, He smote the Philistines even to Gaza. Note, If God remove one useful instrument in the midst of his usefulness, he can, and will, raise up others to carry on and complete the same work that they were employed in and left unfinished. 2. A prophecy of the destruction of the Philistines by famine and war. (1.) By famine, v. 30. "When the people of God, whom the Philistines has wasted, and distressed, and impoverished, shall enjoy plenty again," and the first-born of their poor shall feed (the poorest among them shall have food convenient), then, as for the Philistines, God will kill their root with famine. That which was their strength, and with which they thought themselves established as the tree is by the root, shall be starved and dried up by degrees, as those die that die by famine; and thus he shall slay the remnant: those that escape from one destruction are but reserved for another; and, when there are but a few left, those few shall at length be cut off, for God will make a full end. (2.) By war. When the needy of God's people shall lie down in safety, not terrified with the alarms of war, but delighting in the songs of peace, then every gate and every city of the Philistines shall be howling and crying (v. 31), and there shall be a total dissolution of their state; for from Judea, which lay north of the Philistines, there shall come a smoke (a vast army raising a great dust, a smoke that shall be the indication of a devouring fire at hand), and none of all that army shall be alone in his appointed times; none shall straggle or be missing when they are to engage; but they shall all be vigorous and unanimous in attacking the common enemy, when the time appointed for the doing of it comes. None of them shall decline the public service, as, in Deborah's time, Reuben abode among the sheepfolds and Asher on the sea-shore, Judg. v. 16, 17. When God has work to do he will wonderfully endow and dispose men for it.
