John Gill Bible Commentary

And Abner also spake in the ears of Benjamin,.... Of the inhabitants of the tribe of Benjamin, of which tribe he was, and among whom he had the greatest influence; and with whom it was necessary to take some pains, because of their attachment to the family of Saul, which was of that tribe; and being near to that of Judah, might give David a good deal of trouble, if they were not won over to him: and Abner went also to speak in the ears of David in Hebron; having sounded the elders of Israel, and won their thoughts about the change of government, and found them well disposed to David, and had prevailed upon them to consent to make him king, and had gained the tribe of Benjamin on his side, went and reported to David the success he had: all that seemed good to Israel, and that seemed good to the whole house of Benjamin; how agreeable it was to the elders of Israel, and particularly to the tribe of Benjamin, to have David king over them.
