2 Samuel 13:1-3

Amplified Bible, Classic Edition

13 Absalom son of David had a fair sister whose name was Tamar, and Amnon [her half brother] son of David loved her.

² And Amnon was so troubled that he fell sick for his [half] sister Tamar, for she was a virgin, and Amnon thought it impossible for him to do anything to her.

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