2 Samuel 13:1-2

New Revised Standard Version, Anglicised Catholic Edition

Amnon and Tamar

13 Some time passed. David’s son Absalom had a beautiful sister whose name was Tamar; and David’s son Amnon fell in love with her. ² Amnon was so tormented that he made himself ill because of his sister Tamar, for she was a virgin and it seemed impossible to Amnon to do anything to her.
