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.

(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.
