23 After two full years Absalom had sheepshearers at Baal-hazor, which is near Ephraim, and Absalom invited all the king's sons. 24 And Absalom came to the king and said, "Behold, your servant has sheepshearers. Please let the king and his servants go with your servant." 25 But the king said to Absalom, "No, my son, let us not all go, lest we be burdensome to you." He pressed him, but he would not go but gave him his blessing. 26 Then Absalom said, "If not, please let my brother Amnon go with us." And the king said to him, "Why should he go with you?" 27 But Absalom pressed him until he let Amnon and all the king's sons go with him. 28 Then Absalom commanded his servants, "Mark when Amnon's heart is merry with wine, and when I say to you, 'Strike Amnon,' then kill him. Do not fear; have I not commanded you? Be courageous and be valiant."

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.
