12 And answering him, she said, O my brother, do not put shame on me; it is not right for such a thing to be done in Israel: do not this evil thing. 13 What will become of me in my shame? and as for you, you will be looked down on with disgust by all Israel. Now then, go and make your request to the king, for he will not keep me from you. 14 But he would not give attention to what she said: but being stronger than she, he took her by force, and had connection with her. 15 Then Amnon was full of hate for her, hating her with a hate greater than his earlier love for her. And he said to her, Get up and be gone. 16 And she said to him, Not so, my brother, for this great wrong in sending me away is worse than what you did to me before. But he gave no attention to her. 17 Then he gave a cry to the servant who was waiting on him and said, Put this woman out, and let the door be locked after her. 18 Now she had on a long robe, such as in past times the king's virgin daughters were dressed in. Then the servant put her out, locking the door after her. 19 And Tamar, in her grief, put dust on her head; and she put her hand on her head and went away crying loudly.
20 And her brother Absalom said to her, Has your brother Amnon been with you? but now, let there be an end to your crying, my sister: he is your brother, do not take this thing to heart. So Tamar went on living uncomforted in her brother's house.
21 But when King David had news of all these things he was very angry; but he did not make trouble for Amnon his son, for he was dear to David, being his oldest son. 22 But Absalom said nothing to his brother Amnon, good or bad: for he was full of hate for him, because he had taken his sister Tamar by force.

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.
