5 Jonadab said to him, "Lie down on your bed, and pretend to be ill; and when your father comes to see you, say to him, "Let my sister Tamar come and give me something to eat, and prepare the food in my sight, so that I may see it and eat it from her hand.' " 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.

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.
