8 But Abner son of Ner, the commander of Saul's army, had already gone to Mahanaim with Saul's son Ishbosheth. 9 There he proclaimed Ishbosheth king over Gilead, Jezreel, Ephraim, Benjamin, the land of the Ashurites, and all the rest of Israel. 10 Ishbosheth, Saul's son, was forty years old when he became king, and he ruled from Mahanaim for two years. Meanwhile, the people of Judah remained loyal to David. 11 David made Hebron his capital, and he ruled as king of Judah for seven and a half years.

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.
