Here is, 1. The attempt of his confederate neighbours, the kings of Syria and Israel, upon him. They thought to make themselves masters of Jerusalem, and to set a king of their own in it, Isa 7:6. In this they fell short, but the king of Syria recovered Elath, a considerable port upon the Red Sea, which Amaziah had taken from the Syrians, Kg2 14:22. What can those keep that have lost their religion? Let them expect, thenceforward, to be always on the losing hand. 2. His project to get clear of them. Having forsaken God, he had neither courage nor strength to make head against his enemies, nor could he, with any boldness, ask help of God; but he made his court to the king of Assyria, and got him to come in for his relief. Those whose hearts condemn them will go any where in a day of distress rather than to God. Was it because there was not a God in Israel that he sent to the Assyrian for help? Was the rock of ages removed out of its place, that he stayed himself on this broken reed? The sin itself was its own punishment; for, though it is true that he gained his point (the king of Assyria hearkened to him, and, to serve his own turn, made a descent upon Damascus, whereby he gave a powerful diversion to the king of Syria, Kg2 16:9, and obliged him to let fall his design against Ahaz, carrying the Syrians captive to Kir, as Amos had expressly foretold, Amo 1:5), yet, considering all, he made but a bad bargain; for, to compass this, (1.) He enslaved himself (Kg2 16:7): I am thy servant and thy son, that is, "I will be as dutiful and obedient to thee as to a master or father, if thou wilt but do me this good turn." Had he thus humbled himself to God, and implored his favour, he might have been delivered upon easier terms; he might have saved his money, and needed only to have parted with his sins. But, if the prodigal forsake his father's house, he soon becomes a slave to the worst of masters, Luk 15:15. (2.) He impoverished himself; for he took the silver and gold that were laid up in the treasury both of the temple and of the kingdom, and sent it to the king of Assyria, Kg2 16:8. Both church and state must be squeezed and exhausted, to gratify this his new patron and guardian. I know not what authority he had thus to dispose of the public stock; but it is common for those that have brought themselves into straits by one sin to help themselves out by another; and those that have alienated themselves from God will make no difficulty of alienating any of his rights.

I am thy servant and thy son - I will obey thee in all, and become tributary to thee; only help me against Syria and Israel.

And the king of Assyria hearkened unto him,.... Complied with his request:

for the king of Syria went up against Damascus, and took it; the metropolis of the kingdom of Syria, and so made a powerful diversion in favour of the king of Judah:

and carried the people of it captive to Kir; not Cyrene, as the Vulgate Latin version, a country belonging to Egypt, which the king of Assyria had no power over; but a place in upper Media, as Josephus (p) relates, which belonged to the Assyrian king; see Isa 22:6, compared with Kg2 21:2, of this captivity Amos had prophesied some time before, Amo 1:5.

and slew Rezin; the king of Syria, which also was foretold in the same prophecy.

(p) Antiqu. l. 9. c. 12. sect. 3.

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; Isa 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.
