2. Samuel 3:39

"And the war became long (was protracted) between the house of Saul and the house of David; but David became stronger and stronger, and the house of Saul weaker and weaker." הלך, when connected with another verb or with an adjective, expresses the idea of the gradual progress of an affair (vid., Ges. 131, 3, Anm. 3). The historian sums up in these words the historical course of the two royal houses, as they stood opposed to one another. "The war" does not mean continual fighting, but the state of hostility or war in which they continued to stand towards one another. They concluded no peace, so that David was not recognised by Ishbosheth as king, any more than Ishbosheth by David. Not only is there nothing said about any continuance of actual warfare by Abner or Ishbosheth after the loss of the battle at Gibeon, but such a thing was very improbable in itself, as Ishbosheth was too weak to be able to carry on the war, whilst David waited with firm reliance upon the promise of the Lord, until all Israel should come over to him.

The battle between Joab and Abner did not end the controversy between the two houses of Saul and David, but it is in this chapter working towards a period. Here is, I. The gradual advance of David's interest (Sa2 3:1). II. The building up of his family (Sa2 3:2-5). III. Abner's quarrel with Ish-bosheth, and his treaty with David (Sa2 3:6-12). IV. The preliminaries settled (Sa2 3:13-16). V. Abner's undertaking and attempt to bring Israel over to David (Sa2 3:17-21). VI. The treacherous murder of Abner by Joab, when he was carrying on this matter (Sa2 3:22-27). VII. David's great concern and trouble for the death of Abner (Sa2 3:28-39).

3:39 too strong for me to control: Just as Ishbosheth could not control Abner, David could not control Joab. However, David had faith that the Lord would repay Joab for murdering Abner.
