31 That was the beginning of a long war between those who were loyal to Saul and those loyal to David. As time passed David became stronger and stronger, while Saul's dynasty became weaker and weaker.
2 These are the sons who were born to David in Hebron: The oldest was Amnon, whose mother was Ahinoam from Jezreel. 3 The second was Daniel, whose mother was Abigail, the widow of Nabal from Carmel. The third was Absalom, whose mother was Maacah, the daughter of Talmai, king of Geshur. 4 The fourth was Adonijah, whose mother was Haggith. The fifth was Shephatiah, whose mother was Abital. 5 The sixth was Ithream, whose mother was Eglah, David's wife. These sons were all born to David in Hebron.
6 As the war between the house of Saul and the house of David went on, Abner became a powerful leader among those loyal to Saul.

Commentary on 2 Samuel 3:1-6
(Read 2 Samuel 3:1-6)
The length of this war tried the faith and patience of David, and made his settlement at last the more welcome. The contest between grace and corruption in the hearts of believers, may fitly be compared to this warfare. There is a long war between them, the flesh lusting against the spirit, and the spirit against the flesh; but as the work of holiness is carried on, corruption, like the house of Saul, grows weaker and weaker; while grace, like the house of David, grows stronger and stronger.
