Following the manipulative advice of his cousin Jonadab, Amnon pretended to be ill, arranged for Tamar to attend him, and raped her despite her pleas. His desire then turned to hatred, and he expelled her. David became angry but did not bring effective justice. Absalom said little publicly but hated Amnon. Two years later Absalom arranged a feast and ordered his servants to kill Amnon when he was drinking. Absalom then fled.
