12 One day Abner led Ishbosheth's troops from Mahanaim to Gibeon. 13 About the same time, Joab son of Zeruiah led David's troops out and met them at the pool of Gibeon. The two groups sat down there, facing each other from opposite sides of the pool. 14 Then Abner suggested to Joab, "Let's have a few of our warriors fight hand to hand here in front of us." "All right," Joab agreed. 15 So twelve men were chosen to fight from each side-twelve men of Benjamin representing Ishbosheth son of Saul, and twelve representing David. 16 Each one grabbed his opponent by the hair and thrust his sword into the other's side so that all of them died. So this place at Gibeon has been known ever since as the Field of Swords. 17 A fierce battle followed that day, and Abner and the men of Israel were defeated by the forces of David.

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.
