7-9. So Ahaz sent messengers to Tiglath-pileser—In spite of the assurance given him by Isaiah by two signs, the one immediate, the other remote (Isa 7:14; 8:4), that the confederate kings would not prevail against him, Ahaz sought aid from the Assyrian monarch, to purchase which he sent the treasures of the palace and temple. Tiglath-pileser marched against Damascus, slew Rezin the king, and carried the people of Damascus into captivity to Kir, which is thought to have been the city Karine (now Kerend), in Media.

     16. At that time did king Ahaz send unto the kings of Assyria—"kings," the plural for the singular, which is found in many ancient versions. "At that time," refers to the period of Ahaz' great distress, when, after a succession of defeats, he retreated within the walls of Jerusalem. Either in the same or a subsequent campaign, the Syrian and Israelitish allies marched there to besiege him (see on 2Ki 16:7). Though delivered from this danger, other enemies infested his dominions both on the south and the west.

     20. Tilgath-pilneser . . . distressed him, but strengthened him not—that is, notwithstanding the temporary relief which Tilgath-pilneser afforded him by the conquest of Damascus and the slaughter of Rezin (2Ki 16:9), little advantage resulted from it, for Tilgath-pilneser spent the winter in voluptuous revelry at Damascus; and the connection formed with the Assyrian king was eventually a source of new and greater calamities and humiliation to the kingdom of Judah (2Ch 28:2, 3).
