This heavy prophecy was given to Isaiah in approximately 715 B.C. It described the destruction of Philistia which consisted of five city states located in the Gaza Strip on the Southwest coast of Israel. They were Gaza, Ashdod, Ashkelon, Gath and Ekron. Each functioned as an individual entity with its own king and government. The Philistines had been constant enemies of Israel. They suffered grievously at the hands of Judah in the reign of Uzziah (2 Chronicles 26:6), and had retaliated in the reign of Ahaz (2 Chronicles 28:18). After this they were invaded by Tiglath-Pileser, who penetrated as far as Gaza, which he took (‘Records of the Past,’ vol. v. p. 51) and made tributary, as he also did Ashkelon (‘Ancient Monarchies,’ vol. ii. p. 399). Tiglath-Pileser died shortly before Ahaz, and the present “burden” was given in connection with his death. Isaiah warns Philistia that her rejoicing is premature; Tiglath-Pileser had successors as powerful and as cruel as himself, and these successors did carry out destruction and ravage over the whole land. God is saying here that He will destroy them and cause them to starve and kill their remnant.
