14:28-32 Assurance is given of the destruction of the Philistines and their power, by famine and war. Hezekiah would be more terrible to them than Uzziah had been. Instead of rejoicing, there would be lamentation, for the whole land would be ruined. Such destruction will come upon the proud and rebellious, but the Lord founded Zion for a refuge to poor sinners, who flee from the wrath to come, and trust in his mercy through Christ Jesus. Let us tell all around of our comforts and security, and exhort them to seek the same refuge and salvation.

Isa 14:28-32. Prophecy against Philistia.

To comfort the Jews, lest they should fear that people; not in order to call the Philistines to repentance, since the prophecy was probably never circulated among them. They had been subdued by Uzziah or Azariah (2Ch 26:6); but in the reign of Ahaz (2Ch 28:18), they took several towns in south Judea. Now Isaiah denounces their final subjugation by Hezekiah.

28. In … year … Ahaz died—726 B.C. Probably it was in this year that the Philistines threw off the yoke put on them by Uzziah.
