6 So Amnon lay down and pretended to be sick. And when the king came to see him, Amnon asked him, "Please let my sister Tamar come and cook my favorite dish as I watch. Then I can eat it from her own hands." 7 So David agreed and sent Tamar to Amnon's house to prepare some food for him. 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.
21 When King David heard what had happened, he was very angry. 22 And though Absalom never spoke to Amnon about this, he hated Amnon deeply because of what he had done to his sister. 23 Two years later, when Absalom's sheep were being sheared at Baal-hazor near Ephraim, Absalom invited all the king's sons to come to a feast. 24 He went to the king and said, "My sheep-shearers are now at work. Would the king and his servants please come to celebrate the occasion with me?" 25 The king replied, "No, my son. If we all came, we would be too much of a burden on you." Absalom pressed him, but the king would not come, though he gave Absalom his blessing. 26 "Well, then," Absalom said, "if you can't come, how about sending my brother Amnon with us?" "Why Amnon?" the king asked. 27 But Absalom kept on pressing the king until he finally agreed to let all his sons attend, including Amnon. So Absalom prepared a feast fit for a king.

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.

(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.
