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.
12. Abner … and the servants of Ish-bosheth … went out from Mahanaim to Gibeon—This town was near the confines of Judah, and as the force with which Abner encamped there seemed to have some aggressive design, David sent an army of observation, under the command of Joab, to watch his movements.
