2Sa 13:5 Jonadab said to him, “Lie down on your bed and pretend to be ill. And when your father comes to see you, say to him, ‘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.’”

2Sa 13:7 Then David sent home to Tamar, saying, “Go to your brother Amnon’s house and prepare food for him.”
2Sa 13:10 Then Amnon said to Tamar, “Bring the food into the chamber, that I may eat from your hand.” And Tamar took the cakes she had made and brought them into the chamber to Amnon her brother.
