4. They are deceived in those things which were their confidence and which they thought would have secured their peace to them (v. 19): The daughter of my people cries, cries aloud, because of those that dwell in a far country, because of the foreign enemy that invades them, that comes from a far country to take possession of ours; this occasions the cry; and what is the cry? It is this: Is not the Lord in Zion? Is not her king in her? These were the two things that they had all along buoyed up themselves with and depended upon, (1.) That they had among them the temple of God, and the tokens of his special presence with them. The common cant was, "Is not the Lord in Zion? What danger then need we fear?" And they held by this when the trouble was breaking in upon them. "Surely we shall do well enough, for have we not God among us?" But, when it grew to an extremity, it was an aggravation of their misery that they had thus flattered themselves. (2.) That they had the throne of the house of David. As they had a temple, so they had a monarchy, jure divino—by divine right: Is not Zion's king in her? And will not Zion's God protect Zion's king and his kingdom? Surely he will; but why does he not? "What" (say they) "has Zion neither a God nor a king to stand by her and help her, that she is thus run down and likely to be ruined?" This outcry of theirs reflects upon God, as if his power and promise were broken or weakened; and therefore he returns an answer to it immediately: Why have they provoked me to anger with their graven images? They quarrel with God as if he had dealt unkindly by them in forsaking them, whereas they by their idolatry had driven him from them; they have withdrawn from their allegiance to him, and so have thrown themselves out of this protection. They fret themselves, and curse their king and their God (Isa. viii. 21), when it is their own sin that separates between them and God (Isa. lix. 2); they feared not the Lord, and then what can a king do for them? Hos. x. 3.
