2 Samuel 13:2 ASV

¹  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 because of his sister Tamar; for she was a virgin; and it seemed hard to Amnon to do anything unto 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.

⁴  And he said unto him, Why, O son of the king, art thou thus lean from day to day? wilt thou not tell me? And Amnon said unto him, I love Tamar, my brother Absalom's sister.
