2 Samuel 13:5-9

Jonadab then said to him, “Lie down on your bed and pretend to be ill; when your father comes to see you, say to him, ‘Please have my sister Tamar come and give me food to eat, and have her prepare the food in my sight, so that I may see it and eat from her hand.’ ”

So Amnon lay down and pretended to be ill; when the king came to see him, Amnon said to the king, “Please have my sister Tamar come and make me a couple of pastries in my sight, so that I may eat from her hand.”

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

So Tamar went to her brother Amnon’s house, and he was lying in bed. And she took dough, kneaded it, made pastries in his sight, and baked the pastries.

Then she took the tray and served them to him, but he refused to eat. And Amnon said, “Have everyone leave me.” So everyone left him.
