2 Samuel 13:3-4 NASB1995
But Amnon had a friend whose name was Jonadab, the son of Shimeah, David’s brother; and Jonadab was a very shrewd man. He said to him, “O son of the king, why are you so depressed morning after morning? Will you not tell me?” Then Amnon said to him, “I am in love with Tamar, the sister of my brother Absalom.”
