13:22 Spake - That is, he said nothing at all to him, about that business. He neither debated it with him, nor threatened him for it; but seemed willing to pass it by with brotherly kindness. If he had wholly forborne all discourse with him, it would have raised jealousies in Amnon and David.
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.
