But Amnon had a friend, whose name was Jonadab, the son of Shimeah David’s brother: and Jonadab was a very subtil man.
Context
2 Amnon was so troubled that he became sick because of his sister Tamar, for she was a virgin, and it seemed hard to Amnon to do anything 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.
4 He said to him, “Why, son of the king, are you so sad from day to day? Won’t you tell me?” Amnon said to him, “I love Tamar, my brother Absalom’s sister.”
