8 And Abner the son of Ner, captain of Saul's host, took Ishbosheth the son of Saul, and brought him over to Mahanaim; 9 and made him king over Gilead, and over the Asshurites, and over Jizreel, and over Ephraim, and over Benjamin, and over all Israel. 10 Ishbosheth Saul's son was forty years old when he began to reign over Israel, and he reigned two years. However, the house of Judah followed David. 11 And the time that David was king in Hebron over the house of Judah was seven years and six months.

Commentary on 2 Samuel 2:8-17.
(Read 2 Samuel 2:8-17.)
The nation in general refused David. By this the Lord trained up his servant for future honour and usefulness; and the tendency of true godliness was shown in his behaviour while passing through various difficulties. David was herein a type of Christ, whom Israel would not submit to, though anointed of the Father to be a Prince and a Saviour to them. Abner meant, Let the young men fight before us, when he said, Let them play before us: fools thus make a mock at sin. But he is unworthy the name of a man, that can thus trifle with human blood.
