Matthew Henry on 1 Kings 1:5-10
David had much affliction in his children. Amnon and Absalom had both been his grief; the one his first-born, the other his third, Sa2 3:2, Sa2 3:3. His second, whom he had by Abigail, we will suppose he had comfort in; his fourth was Adonijah (Sa2 3:4); he was one of those that were born in Hebron; we have heard nothing of him till now, and here we are told that he was a comely person, and that he was next in age, and (as it proved) next in temper to Absalom, Kg1 1:6.
