Amnon in Wikipedia
According to the Bible, Amnon (Hebrew: אַמְנוֹן, "faithful") was
the oldest son of David, King of Israel, with his wife,
Ahinoam, who is described as "the Jezreelitess". (1 Chronicles
3:1 , 2 Samuel 3:2 ). Although he was the heir-apparent to
David's throne, Amnon is best remembered for the rape of his
half-sister Tamar, daughter of David with Maachah.
Despite the biblical prohibition to sexual relations between
half-brothers and sisters, (Leviticus 18:11 ) Amnon had an
overwhelming desire for her. He took advice from his cousin,
Jonadab the son of Shimeah, David's brother, to lure Tamar
into his quarters by pretending to be sick and desiring her to
cook a special meal for him. While in his quarters, and
ignoring her protests, he raped her.
Two years later, to avenge his sister, Absalom, Amnon's half-
brother and Tamar's full brother, sent his servants to kill
Amnon at a feast to which he had invited all the king's sons.
