2 Samuel 13:3-5

New Revised Standard Version, Anglicised

³ But Amnon had a friend whose name was Jonadab, the son of David’s brother Shimeah; and Jonadab was a very crafty man. ⁴ He said to him, ‘O son of the king, why are you so haggard morning after morning? Will you not tell me?’ Amnon said to him, ‘I love Tamar, my brother Absalom’s sister.’ 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 something to eat, and prepare the food in my sight, so that I may see it and eat it from her hand.”’
