I. It is here foretold that the Philistines, the usurpers, shall be dispossessed and quite extirpated. In general, here is a woe to them (v. 5), which, coming from God, denotes all misery: The word of the Lord is against them—the word of the former prophets, which, though not yet accomplished, will be in its season, Isa. xiv. 31. This word, now by this prophet, is against them. Note, Those are really in a woeful condition that have the word of the Lord against them, for no word of his shall fall to the ground. Those that rebel against the precepts of God's word shall have the threatenings of the word against them. The effect will be no less than their destruction, 1. God himself will be the author of it: "I will even destroy thee, who can make good what I say and will." 2. It shall be a universal destruction; it shall extend itself to all parts of the land, both city and country: Gaza shall be forsaken, though now a populous city. It was foretold (Jer. xlvii. 6) that baldness should come upon Gaza; Alexander the Great razed that city, and we find (Acts viii. 26) that Gaza was a desert. Ashkelon shall be a desolation, a pattern of desolation. Ashdod shall be driven out at noon-day; in the extremity of the scorching heat they shall have no shade, no shelter to protect them; but then, when most incommoded by the weather, they shall be forced away into captivity, which will be an aggravating circumstance of it. Ekron likewise shall be rooted up, that had been long taking root. The land of the Philistines shall be dispeopled; there shall be no inhabitant, v. 5. God made the earth to be inhabited (Isa. xlv. 18), otherwise he would have made it in vain; but, if men do not answer the end of their creation in serving God, it is just with God that the earth should not answer the end of its creation in serving them for a habitation; man's sin has sometimes subjected it to this vanity. 3. It shall be an utter destruction. The sea-coast, which used to be a harbour for ships and a habitation for merchants, shall now be deserted, and be only cottages for shepherds and folds for flocks (v. 6), and then perhaps put to better use than when it was possessed by the lords of the Philistines.
