2 Samuel 13:4-6

13:4 He asked Amnon, “Why are you, the king’s son, so depressed every morning? Can’t you tell me?” So Amnon said to him, “I’m in love with Tamar the sister of my brother Absalom.” 13:5 Jonadab replied to him, “Lie down on your bed and pretend to be sick. When your father comes in to see you, say to him, ‘Please let my sister Tamar come in so she can fix some food for me. Let her prepare the food in my sight so I can watch. Then I will eat from her hand.’”

13:6 So Amnon lay down and pretended to be sick. When the king came in to see him, Amnon said to the king, “Please let my sister Tamar come in so she can make a couple of cakes in my sight. Then I will eat from her hand.”

2 Samuel 13:20

13:22 But Absalom said nothing to Amnon, either bad or good, yet Absalom hated Amnon because he had humiliated his sister Tamar.

2 Samuel 13:32

13:32 Jonadab, the son of David’s brother Shimeah, said, “My lord should not say, ‘They have killed all the young men who are the king’s sons.’ For only Amnon is dead. This is what Absalom has talked about from the day that Amnon humiliated his sister Tamar.
