8 When Tamar arrived at Amnon's house, she went to the place where he was lying down so he could watch her mix some dough. Then she baked his favorite dish for him. 9 But when she set the serving tray before him, he refused to eat. "Everyone get out of here," Amnon told his servants. So they all left. 10 Then he said to Tamar, "Now bring the food into my bedroom and feed it to me here." So Tamar took his favorite dish to him. 11 But as she was feeding him, he grabbed her and demanded, "Come to bed with me, my darling sister." 12 "No, my brother!" she cried. "Don't be foolish! Don't do this to me! Such wicked things aren't done in Israel. 13 Where could I go in my shame? And you would be called one of the greatest fools in Israel. Please, just speak to the king about it, and he will let you marry me." 14 But Amnon wouldn't listen to her, and since he was stronger than she was, he raped her. 15 Then suddenly Amnon's love turned to hate, and he hated her even more than he had loved her. "Get out of here!" he snarled at her. 16 "No, no!" Tamar cried. "Sending me away now is worse than what you've already done to me." But Amnon wouldn't listen to her. 17 He shouted for his servant and demanded, "Throw this woman out, and lock the door behind her!" 18 So the servant put her out and locked the door behind her. She was wearing a long, beautiful robe, as was the custom in those days for the king's virgin daughters. 19 But now Tamar tore her robe and put ashes on her head. And then, with her face in her hands, she went away crying.
20 Her brother Absalom saw her and asked, "Is it true that Amnon has been with you? Well, my sister, keep quiet for now, since he's your brother. Don't you worry about it." So Tamar lived as a desolate woman in her brother Absalom's house.

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.
