2 Samuel 13:4

1 After this, Absalom the son of David had a beautiful sister, whose name was Tamar; and Amnon the son of David loved her.

2 Amnon was so troubled that he became sick because of his sister Tamar, for she was a virgin, and it seemed hard to Amnon to do anything to her.

3 But Amnon had a friend whose name was Jonadab the son of Shimeah, David’s brother; and Jonadab was a very subtle man.

4 He said to him, “Why, son of the king, are you so sad from day to day? Won’t you tell me?” Amnon said to him, “I love Tamar, my brother Absalom’s sister.”

5 Jonadab said to him, “Lay down on your bed and pretend to be sick. When your father comes to see you, tell him, ‘Please let my sister Tamar come and give me bread to eat, and prepare the food in my sight, that I may see it and eat it from her hand.’”

6 So Amnon lay down and faked being sick. When the king came to see him, Amnon said to the king, “Please let my sister Tamar come and make me a couple of cakes in my sight, that I may eat from her hand.”

7 Then David sent home to Tamar, saying, “Go now to your brother Amnon’s house, and prepare food for him.”
