The hearts of the men of Israel are after Absalom - It is very difficult to account for this general defection of the people. Several reasons are given:

1. David was old or afflicted, and could not well attend to the administration of justice in the land.

2. It does appear that the king did not attend to the affairs of state, and that there were no properly appointed judges in the land; see 2 Samuel 15:3.

3. Joab's power was overgrown; he was wicked and insolent, oppressive to the people, and David was afraid to execute the laws against him.

4. There were still some partisans of the house of Saul, who thought the crown not fairly obtained by David.

5. David was under the displeasure of the Almighty, for his adultery with Bath-sheba, and his murder of Uriah; and God let his enemies loose against him.

6. There are always troublesome and disaffected men in every state, and under every government; who can never rest, and are ever hoping for something from a change.

7. Absalom appeared to be the real and was the undisputed heir to the throne; David could not, in the course of nature, live very long; and most people are more disposed to hail the beams of the rising, than exult in those of the setting, sun.

No doubt some of these causes operated, and perhaps most of them exerted less or more influence in this most scandalous business.

And there came a messenger to David,.... Perhaps one of the two hundred that went with Absalom, ignorant of his design; which, when discovered, he disapproved of, and got away from him, and came to David, and informed him how things were:

saying, the hearts of the men of Israel are after Absalom; to make him king.

David's flight from Jerusalem. - 2 Samuel 15:13, 2 Samuel 15:14. When this intelligence reached David, "The heart of the men of Israel is after Absalom" (אהר היה, as in 2 Samuel 2:10, to be attached to a person as king; see at 1 Samuel 12:14), he said to his servants that were with him in Jerusalem, "Arise, let us flee, for there will be no escape for us from Absalom! Make speed to depart, lest he overtake us suddenly, and drive the calamity (the judgment threatened in 2 Samuel 12:10-11) over us, and smite the city with the edge of the sword." David was perhaps afraid that Jerusalem might fall into Absalom's power through treachery, and therefore resolved to fly as speedily as possible, not only in order to prevent a terrible massacre, but also to give his own faithful adherents time to assemble.

And there came a messenger to David, saying, The hearts of the men of Israel are after Absalom.

2Sa 15:13-37. David Flees from Jerusalem.

15:13-23 David determined to quit Jerusalem. He took this resolve, as a penitent submitting to the rod. Before unrighteous Absalom he could justify himself, and stand out; but before the righteous God he must condemn himself, and yield to his judgments. Thus he accepts the punishment of his sin. And good men, when they themselves suffer, are anxious that others should not be led to suffer with them. He compelled none; those whose hearts were with Absalom, to Absalom let them go, and so shall their doom be. Thus Christ enlists none but willing followers. David cannot bear to think that Ittai, a stranger and an exile, a proselyte and a new convert, who ought to be encouraged and made easy, should meet with hard usage. But such value has Ittai for David's wisdom and goodness, that he will not leave him. He is a friend indeed, who loves at all times, and will adhere to us in adversity. Let us cleave to the Son of David, with full purpose of heart, and neither life nor death shall separate us from his love.
