But - Literally, "and." Thus had Gaza done, and thus would God do; "I will send a fire upon Gaza." The sentence on Gaza stands out, probably in that it was first in power and in sin. It was the merchant-city of the five; the caravans parted from it or passed through it; and so this sale of the Jewish captives was ultimately effected through them. First in sin, first in punishment. Gaza was strong by nature and by art. "The access to it also," Arrian notices , "lay through deep sand." We do not hear of its being taken, except in the first times of Israel under the special protection of God Judges 1:1-2, Judges 1:18, or by great conquerors. All Philistia, probably, submitted to David; we hear of no special conquest of its towns 2-Samuel 8:1. Its siege cost Alexander 2 months , with all the aid of the engines with which he had taken Tyre, and the experience which he had there gained. The Egyptian accounts state, that when besieged by Tothmosis III it capitulated . Thenceforth, it had submitted neither to Egypt nor Assyria. Yet Amos declared absolutely, that Gaza should be destroyed by fire, and it was so. Sennacherib first, then, after Jeremiah had foretold anew the destruction of Gaza, Ashkelon, and the Philistines, Pharaoh Necho "smote Gaza" Jeremiah 47:1. Yet who, with human foresight only, would undertake to pronounce the destruction of a city so strong?

But I will send a fire on the wall of Gaza,.... An enemy that shall pull down and destroy the walls of it: this was fulfilled in the times of Uzziah, under whom Amos prophesied; and very likely in a very short time after this prophecy, who went out and warred against the Philistines, and broke down the wall of Gaza, 2-Chronicles 26:6; or else in the times of Hezekiah, who smote the Philistines unto Gaza, and the borders thereof, 2-Kings 18:8; or however in the times of Nebuchadnezzar, according to the prophecy of Jeremiah, Jeremiah 25:20; as also in the times of Alexander the great, who, after he had taken Tyre, besieged Gaza, and after two months' siege took it, as Diodorus Siculus relates (p); the wall being undermined and thrown down, he entered in at the ruins of it, as Curtius (q) says; in the times of the Maccabees the suburbs of it were burnt by Jonathan, and the place taken:
"61 From whence he went to Gaza, but they of Gaza shut him out; wherefore he laid siege unto it, and burned the suburbs thereof with fire, and spoiled them. 62 Afterward, when they of Gaza made supplication unto Jonathan, he made peace with them, and took the sons of their chief men for hostages, and sent them to Jerusalem, and passed through the country unto Damascus.'' (1 Maccabees 11)
which shall devour the palaces thereof; the palaces of the governor, and of other great men in it; (the governor of it, when Alexander took it, was Batis;) and the stately towers of it, of which there were many. This city was about fifteen miles south of Askelon, and about four or five north of the river Bezor, and at a small distance from the Mediterranean. It was situated on an eminence, surrounded with the most beautiful and fertile valleys, watered by the above mentioned river, and a number of other springs; and at a further distance encompassed on the inland side with hills, all planted with variety of fine fruit trees. The city itself was strong, both by its situation, and by the stout "walls" and stately "bowers" that surrounded it, and built after the Philistine manner (r) Arrian also says (s), it was a great city built on high ground, and encompassed with a strong wall, and was distant from the sea at least two and a half miles; See Gill on Acts 8:26.

fire--that is, the flame of war (Numbers 21:28; Isaiah 26:11). Hezekiah fulfilled the prophecy, smiting the Philistines unto Gaza (2-Kings 18:8). Foretold also by Isaiah 14:29, Isaiah 14:31.

A fire - Desolating judgments. Gaza - All the power and strength of Palestine is here included.
