21 But when king David heard of all these things, he was very angry. 22 Absalom spoke to Amnon neither good nor bad; for Absalom hated Amnon, because he had forced his sister Tamar. 23 It happened after two full years, that Absalom had sheepshearers in Baal Hazor, which is beside Ephraim: and Absalom invited all the king’s sons. 24 Absalom came to the king, and said, “See now, your servant has sheepshearers. Please let the king and his servants go with your servant.” 25 The king said to Absalom, “No, my son, let us not all go, lest we be burdensome to you.” He pressed him; however he would not go, but blessed him. 26 Then Absalom said, “If not, please let my brother Amnon go with us.”
The king said to him, “Why should he go with you?” 27 But Absalom pressed him, and he let Amnon and all the king’s sons go with him. 28 Absalom commanded his servants, saying, “Mark now, when Amnon’s heart is merry with wine; and when I tell you, ‘Strike Amnon,’ then kill him. Don’t be afraid. Haven’t I commanded you? Be courageous, and be valiant!” 29 The servants of Absalom did to Amnon as Absalom had commanded. Then all the king’s sons arose, and every man got him up on his mule, and fled.

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.
