2 Samuel 13:2-4

Tree of Life Version

² But Amnon was so frustrated that he fell sick because of his sister Tamar, for she was a virgin and it seemed impossible in Amnon to do anything to her. ³ However, Amnon had a friend named Jonadab son of Shimeah, David’s brother, and Jonadab was a very shrewd man. ⁴ So he said to him, “Why are you, the king’s son, so miserable morning after morning? Won’t you tell me?”

Amnon told him, “I’m in love with Tamar, my brother Absalom’s sister.”
