John Gill's Bible Commentary Ver. 6. And it came to pass, while there was war between the house of Saul and the house of David , etc.] As long as that continued, as it did until the following quarrel happened between Ishbosheth and Abner: that Abner made himself strong for the house of Saul ; or was strongly in the interest of that house, and used his utmost endeavours to support and confirm it.
Matthew Henry Commentary
Verses 1-6 - The length of this war tried the faith and patience of David, and mad his settlement at last the more welcome. The contest between grace an corruption in the hearts of believers, may fitly be compared to thi warfare. There is a long war between them, the flesh lusting agains the spirit, and the spirit against the flesh; but as the work of holiness is carried on, corruption, like the house of Saul, grow weaker and weaker; while grace, like the house of David, grows stronge and stronger.
