John Gill Bible Commentary

And all the people took notice of it,.... Not only of his oath, that he would not eat food till evening, but of his whole conduct at the funeral of Abner; the sorrow he expressed for his death, and the oration he made on account of it, in which he pretty severely reflected on his murderer: and it pleased them; that he showed such a concern for his death, and that it was a clear case he had no hand in it: as whatsoever the king did pleased all the people; what he did at this time, burying Abhor with so much pomp and ceremony; and indeed he had so much the hearts of the people, and such a share in their affections, and they had such an high opinion of him, that all that he did in public and private affairs they reckoned well done; they were highly approved of by them, such an interest had he in them.
