New King James Version

Amnon and Tamar

13 After this ^(A)Absalom the son of David had a lovely sister, whose name was ^(B)Tamar; and ^(C)Amnon the son of David loved her. ² Amnon was so distressed over his sister Tamar that he became sick; for she was a virgin. And it was improper for Amnon to do anything to her.
