Sargon had established the complete dominion of Assyria over the Philistines. Hence, the object of Hezekiah's Philistine campaign was not so much conquest as opposition to the Assyrian power. How successful it was is indicated in the Assyrian records by the number of towns in this quarter which Sennacherib recovered before he proceeded against Jerusalem.

From the tower of the watchmen - See the same words, 2 Kings 17:9 (note). It seems a proverbial mode of expression: he reduced every kind of fortification; nothing was able to stand before him.

He smote the Philistines even unto Gaza, and the borders thereof,.... Who in his father's time had invaded Judah, and taken many cities and towns in it, which Hezekiah now recovered, and drove them to their own territories, of which Gaza was one; see 2 Chronicles 28:18.

from the tower of the watchmen to the fenced city; that is, places both great and small, cities, towns, and villages; of this phrase, see 2 Kings 17:9.

Hezekiah smote the Philistines to Gaza, and their territory from the tower of the watchmen to the fortified city, i.e., all the towns from the least to the greatest (see at 2 Kings 17:9). He thus chastised these enemies for their invasion of Judah in the time of Ahaz, wrested from them the cities which they had taken at that time (2 Chronicles 28:18), and laid waste all their country to Gaza, i.e., Ghuzzeh, the most southerly of the chief cities of Philistia (see at Joshua 13:3). This probably took place after the defeat of Sennacherib (cf. 2 Chronicles 32:22-23).

He smote the Philistines, even unto Gaza, and the borders thereof, {c} from the tower of the watchmen to the fenced city.

(c) Read 2Ki 17:9.

Gaza: Heb. Azzah

18:1-8 Hezekiah was a true son of David. Some others did that which was right, but not like David. Let us not suppose that when times and men are bad, they must needs grow worse and worse; that does not follow: after many bad kings, God raised one up like David himself. The brazen serpent had been carefully preserved, as a memorial of God's goodness to their fathers in the wilderness; but it was idle and wicked to burn incense to it. All helps to devotion, not warranted by the word of God, interrupt the exercise of faith; they always lead to superstition and other dangerous evils. Human nature perverts every thing of this kind. True faith needs not such aids; the word of God, daily thought upon and prayed over, is all the outward help we need.
