20 And Absalom her brother said to her, Has Amnon thy brother been with thee? and now, my sister, be still: he is thy brother; take not this thing to heart. And Tamar remained, and [that] desolate, in her brother Absalom's house.
21 And king David heard of all these things, and he was very angry. 22 And Absalom spoke to Amnon neither good nor bad; for Absalom hated Amnon, because he had humbled his sister Tamar.

Commentary on 2 Samuel 13:1-20
(Read 2 Samuel 13:1-20)
From henceforward David was followed with one trouble after another. Adultery and murder were David's sins, the like sins among his children were the beginnings of his punishment: he was too indulgent to his children. Thus David might trace the sins of his children to his own misconduct, which must have made the anguish of the chastisement worse. Let no one ever expect good treatment from those who are capable of attempting their seduction; but it is better to suffer the greatest wrong than to commit the least sin.
Commentary on 2 Samuel 13:21-29
(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.
