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.

(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.
