John Gill Commentary 2 Samuel 15:13

"And there came a messenger to David, saying, The hearts of the men of Israel are after Absalom." — 2 Samuel 15:13 (ASV)

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.
