6 So Amnon lay down, and pretended to be ill; and when the king came to see him, Amnon said to the king, "Please let my sister Tamar come and make a couple of cakes in my sight, so that I may eat from her hand." 7 Then David sent home to Tamar, saying, "Go to your brother Amnon's house, and prepare food for him." 8 So Tamar went to her brother Amnon's house, where he was lying down. She took dough, kneaded it, made cakes in his sight, and baked the cakes. 9 Then she took the pan and set them out before him, but he refused to eat. Amnon said, "Send out everyone from me." So everyone went out from him. 10 Then Amnon said to Tamar, "Bring the food into the chamber, so that I may eat from your hand." So Tamar took the cakes she had made, and brought them into the chamber to Amnon her brother. 11 But when she brought them near him to eat, he took hold of her, and said to her, "Come, lie with me, my sister." 12 She answered him, "No, my brother, do not force me; for such a thing is not done in Israel; do not do anything so vile! 13 As for me, where could I carry my shame? And as for you, you would be as one of the scoundrels in Israel. Now therefore, I beg you, speak to the king; for he will not withhold me from you." 14 But he would not listen to her; and being stronger than she, he forced her and lay with her. 15 Then Amnon was seized with a very great loathing for her; indeed, his loathing was even greater than the lust he had felt for her. Amnon said to her, "Get out!" 16 But she said to him, "No, my brother; for this wrong in sending me away is greater than the other that you did to me." But he would not listen to her. 17 He called the young man who served him and said, "Put this woman out of my presence, and bolt the door after her." 18 (Now she was wearing a long robe with sleeves; for this is how the virgin daughters of the king were clothed in earlier times. ) So his servant put her out, and bolted the door after her. 19 But Tamar put ashes on her head, and tore the long robe that she was wearing; she put her hand on her head, and went away, crying aloud as she went.
20 Her brother Absalom said to her, "Has Amnon your brother been with you? Be quiet for now, my sister; he is your brother; do not take this to heart." So Tamar remained, a desolate woman, in her brother Absalom's house.
21 When King David heard of all these things, he became very angry, but he would not punish his son Amnon, because he loved him, for he was his firstborn. 22 But Absalom spoke to Amnon neither good nor bad; for Absalom hated Amnon, because he had raped his sister Tamar. 23 After two full years Absalom had sheepshearers at Baal-hazor, which is near Ephraim, and Absalom invited all the king's sons. 24 Absalom came to the king, and said, "Your servant has sheepshearers; will the king and his servants please go with your servant?" 25 But the king said to Absalom, "No, my son, let us not all go, or else we will be burdensome to you." He pressed him, but he would not go but gave him his blessing. 26 Then Absalom said, "If not, please let my brother Amnon go with us." The king said to him, "Why should he go with you?" 27 But Absalom pressed him until he let Amnon and all the king's sons go with him. Absalom made a feast like a king's feast.

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.
