7:1-9 Ungodly men are often punished by others as bad as themselves. Being in great distress and confusion, the Jews gave up all for lost. They had made God their enemy, and knew not how to make him their friend. The prophet must teach them to despise their enemies, in faith and dependence on God. Ahaz, in fear, called them two powerful princes. No, says the prophet, they are but tails of smoking firebrands, burnt out already. The two kingdoms of Syria and Israel were nearly expiring. While God has work for the firebrands of the earth, they consume all before them; but when their work is fulfilled, they will be extinguished in smoke. That which Ahaz thought most formidable, is made the ground of their defeat; because they have taken evil counsel against thee; which is an offence to God. God scorns the scorners, and gives his word that the attempt should not succeed. Man purposes, but God disposes. It was folly for those to be trying to ruin their neighbours, who were themselves near to ruin. Isaiah must urge the Jews to rely on the assurances given them. Faith is absolutely necessary to quiet and compose the mind in trials.
8. head—that is, in both Syria and Israel the capital shall remain as it is; they shall not conquer Judah, but each shall possess only his own dominions.
threescore and five … not a people—As these words break the symmetry of the parallelism in this verse, either they ought to be placed after "Remaliah's son," in Isa 7:9, or else they refer to some older prophecy of Isaiah, or of Amos (as the Jewish writers represent), parenthetically; to which, in Isa 7:8, the words, "If ye will not believe … not be established," correspond in parallelism. One deportation of Israel happened within one or two years from this time, under Tiglath-pileser (2Ki 15:29). Another in the reign of Hoshea, under Shalmaneser (2Ki 17:1-6), was about twenty years after. But the final one which utterly "broke" up Israel so as to be "not a people," accompanied by a colonization of Samaria with foreigners, was under Esar-haddon, who carried away Manasseh, king of Judah, also, in the twenty-second year of his reign, sixty-five years from the utterance of this prophecy (compare Ezr 4:2, 3, 10, with 2Ki 17:24; 2Ch 33:11) [Usher]. The event, though so far off, was enough to assure the people of Judah that as God, the Head of the theocracy, would ultimately interpose to destroy the enemies of His people, so they might rely on Him now.
