31 Now there was a long war between Saul's people and David's people; and David became stronger and stronger, but those on Saul's side became more and more feeble.
2 While David was in Hebron he became the father of sons: the oldest was Amnon, son of Ahinoam of Jezreel; 3 And the second, Chileab, whose mother was Abigail, the wife of Nabal the Carmelite; and the third, Absalom, son of Maacah, the daughter of Talmai, king of Geshur; 4 And the fourth, Adonijah, the son of Haggith; and the fifth, Shephatiah, the son of Abital; 5 And the sixth, Ithream, whose mother was David's wife Eglah. These were the sons of David, whose birth took place in Hebron.
Matthew Henry's Commentary on 2 Samuel 3:1-5
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.
