2-а Самуїлова 2:27

Joab replied, "If thou hadst not spoken (i.e., challenged to single combat, Sa2 2:14), the people would have gone away in the morning, every one from his brother," i.e., there would have been no such fratricidal conflict at all. The first כּי introduces the substance of the oath, as in Sa1 25:34; the second gives greater force to it (vid., Ewald, 330, b.). Thus Joab threw all the blame of the fight upon Abner, because he had been the instigator of the single combat; and as that was not decisive, and was so bloody in its character, the two armies had felt obliged to fight it out. But he then commanded the trumpet to be blown for a halt, and the pursuit to be closed.

David had paid due respect to the memory of Saul his prince and Jonathan his friend, and what he did was as much his praise as theirs; he is now considering what is to be done next. Saul is dead, now therefore David arise. I. By direction from God he went up to Hebron, and was there anointed king (Sa2 2:1-4). II. He returned thanks to the men of Jabesh-Gilead for burying Saul (Sa2 2:5-7). III. Ishbosheth, the son of Saul, is set up in opposition to him (Sa2 2:8-11). IV. A warm encounter happens between David's party and Ishbosheth's, in which, 1. Twelve of each side engaged hand to hand and were all slain (Sa2 2:12-16). 2. Saul's party was beaten (Sa2 2:17). 3. Asahel, on David's side, was slain by Abner (Sa2 2:18-23). 4. Joab, at Abner's request, sounds a retreat, (Sa2 2:24-28). 5. Abner makes the best of his way (Sa2 2:29), and the loss on both sides is computed (Sa2 2:30-32). So that here we have an account of a civil war in Israel, which, in process of time, ended in the complete settlement of David on the throne.
