The king of Assyria hearkened unto him - It is said, 2 Chronicles 28:20, that Tilgath-pilneser distressed him, but strengthened him not.
Though he came against the Syrians, and took Damascus, and slew Rezin, yet he did not help Ahaz against the Philistines, nor did he lend him any forces to assist against Israel; and he distressed him by taking the royal treasures, and the treasures of the temple, and did him little service for so great a sacrifice. He helped him a little, but distressed him on the whole.
It appears that, about this time, Pekah king of Israel nearly ruined Judea: it is said, 2 Chronicles 28:6, that he slew one hundred thousand valiant men in one day; and that he carried away captive to Samaria two hundred thousand women and children, and much spoil; but, at the instance of the prophet Oded, these were all sent back, fed and clothed, 2 Chronicles 28:8-16.
The submission of Judah, which Ahaz proffered, would be of the utmost importance in connection with any projects that might be entertained of Egyptian conquests. Naturally, Damascus was the first object of attack. It was the head of the confederacy, and it lay nearest to an army descending upon Lower Syria, as all Asiatic armies would descend, from the north. It appears from an inscription of Tiglath-pileser‘s, that Rezin met him in the field, was defeated, and slain. An attack upon Pekah followed. Now probably it was that the entire trans-Jordanic region was overrun: and that the Reubenites, the Gadites, and the half-tribe of Manasseh, were carried into captivity 1 Chronicles 5:26. Megiddo and Dor appear also to have been occupied, and the Arabs of the south chastised. Tiglathpileser then returned to Damascus, where a son of Rezin had assumed the crown; he besieged and took the city, and punished Rezin‘s son with death. Tiglath-pileser appears by one of his inscriptions to have held a court at Damascus, to which it is probable that the tributary kings of the neighborhood were summoned to pay their tributes and do homage for their kingdoms. Among the tributes brought to him at this time, those of Judaea, Edom, Ammon, Moab, Gaza, Ascalon, and Tyre, are mentioned.
Kir - Kir is mentioned by Amos Amos 9:7 as the country from which the Syrians came. It is joined by Isaiah Isaiah 22:6 with Elam or Elymais. Its position can only be conjectured. Perhaps the word designates a region adjoining Elymais, in the extreme southeastern limits of Assyria.
