2 Samuel 13:32-33

32But Jonadab, son of David’s brother Shimeah, spoke up: “My lord must not think they have killed all the young men, the king’s sons, because only Amnon is dead. In fact, Absalom has planned this ever since the day Amnon disgraced his sister Tamar.

33So now, my lord the king, don’t take seriously the report that says all the king’s sons are dead. Only Amnon is dead.”
