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.

Volume 1-7
24. Came to the king. Absalom’s deep guile is revealed in this invitation to David. He hardly expected his father to come, but by urging him to do so, he would help to allay suspicion and would thus encourage the attendance of Amnon.
