28 Now Absalom had given orders to his servants, saying, Now take note when Amnon's heart is glad with wine; and when I say to you, Make an attack on Amnon, then put him to death without fear: have I not given you orders? be strong and without fear. 29 So Absalom's servants did to Amnon as Absalom had given them orders. Then all the king's sons got up, and every man got on his beast and went in flight.

(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.
