2 Samuel 13:3

And Samuel said to Jesse, “Are these all the young men?” And he said, “There remains yet the youngest, and behold, he is shepherding the sheep.” Then Samuel said to Jesse, “Send and bring him, for we will not turn around until he comes here.”

But Jonadab, the son of Shimeah, David’s brother, answered and said, “Do not let my lord suppose they have put to death all the young men, the king’s sons, for Amnon alone has died; because by the intent of Absalom this has been set since the day that he violated his sister Tamar.
