23 Two years later, when Absalom's sheep were being sheared at Baal-hazor near Ephraim, Absalom invited all the king's sons to come to a feast. 24 He went to the king and said, "My sheep-shearers are now at work. Would the king and his servants please come to celebrate the occasion with me?" 25 The king replied, "No, my son. If we all came, we would be too much of a burden on you." Absalom pressed him, but the king would not come, though he gave Absalom his blessing. 26 "Well, then," Absalom said, "if you can't come, how about sending my brother Amnon with us?" "Why Amnon?" the king asked. 27 But Absalom kept on pressing the king until he finally agreed to let all his sons attend, including Amnon. So Absalom prepared a feast fit for a king. 28 Absalom told his men, "Wait until Amnon gets drunk; then at my signal, kill him! Don't be afraid. I'm the one who has given the command. Take courage and do it!" 29 So at Absalom's signal they murdered Amnon. Then the other sons of the king jumped on their mules 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.
