2 Samuel 13:3-5

21st Century King James Version

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 And he said unto him, “Why art thou, being the king’s son, lean from day to day? Wilt thou not tell me?” And Amnon said unto him, “I love Tamar, my brother Absalom’s sister.”

⁵ And Jonadab said unto him, “Lay thee down on thy bed and make thyself sick; and when thy father cometh to see thee, say unto him, ‘I pray thee, let my sister Tamar come and give me meat, and dress the meat in my sight, that I may see it and eat it at her hand.’”
