And Amnon was so vexed, that he fell sick for his sister Tamar; for she was
a virgin; and Amnon thought it hard for him to do any thing to her.
But Amnon had a friend, whose name was
Jonadab, the son of Shimeah David's brother: and Jonadab was
a very subtil man.
And he said unto him, Why art
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.
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.
