21 When King David heard of all these things, he became very angry, but he would not punish his son Amnon, because he loved him, for he was his firstborn.

Matthew Henry's Commentary on 2 Samuel 13:21

Commentary on 2 Samuel 13:21-29

(Read 2 Samuel 13:21-29)

Observe the aggravations of Absalom's sin: he would have Ammon slain, when least fit to go out of the world. He engaged his servants in the guilt. Those servants are ill-taught who obey wicked masters, against God's commands. Indulged children always prove crosses to godly parents, whose foolish love leads them to neglect their duty to God.
