2 Samuel 13:1-4

1Now it was after this that 1Absalom the son of David had a beautiful sister whose name was 2Tamar, and 3Amnon the son of David was in love with her.

2But Amnon was so frustrated on account of his sister Tamar that he made himself ill, for she was a virgin, and it 4seemed too difficult to Amnon to do anything to her.

3But Amnon had a friend whose name was Jonadab, the son of 56Shimeah, David’s brother; and Jonadab was a very clever man.

4And he said to him, “Why are you, the king’s son, so depressed morning after morning? Will you not tell me?” So Amnon said to him, “I am in love with Tamar, the sister of my brother Absalom.”
