2 Samuel 13:1-3

21st Century King James Version

13 And it came to pass after this that Absalom the son of David had a fair sister, whose name was Tamar; and Amnon the son of David loved her.

² 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.

³ But Amnon had a friend whose name was Jonadab, the son of Shimeah David’s brother; and Jonadab was a very subtle man.
