But I will send a fire on the wall of Gaza, which shall devour the palaces thereof:
But I will send a fire on the wall of Gaza - i:e., the flame of war (Numbers 21:28; Isaiah 26:11, "The fire of thine enemies shall devour them"). For "but" translate and: so Gaza had done: and so accordingly will the Lord reward her.
On the wall of Gaza, which shall devour the palaces thereof. Hezekiah fulfilled the prophecy, "smiting the Philistines unto Gaza and the borders thereof, from the tower of the watchmen to the fenced city" (2 Kings 18:8). Sennacherib also smote it; then Pharaoh-necho (Isaiah 47:1); then Alexander, after a two months' siege. Foretold also by Isaiah 14:29; Isaiah 14:31.
