31 Now there was a long war between the house of Saul and the house of David. But David grew stronger and stronger, and the house of Saul grew weaker and weaker.
2 Sons were born to David in Hebron: His firstborn was Amnon by Ahinoam the Jezreelitess; 3 his second, Chileab, by Abigail the widow of Nabal the Carmelite; the third, Absalom the son of Maacah, the daughter of Talmai, king of Geshur; 4 the fourth, Adonijah the son of Haggith; the fifth, Shephatiah the son of Abital; 5 and the sixth, Ithream, by David's wife Eglah. These were born to David in Hebron.
6 Now it was so, while there was war between the house of Saul and the house of David, that Abner was strengthening his hold on the house of Saul.
Matthew Henry's Commentary on 2 Samuel 3:1-6
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.
