Judas Iscariot was the disciple who betrayed Jesus of Nazareth, according to the Christian Bible. The Gospels -- the first four books of the New Testament -- tell of authorities in Jerusalem who plot to kill Jesus during a religious festival but need to avoid a riot. For reasons unknown, Judas offers to help and is paid 30 silver coins. At a meal known as the Last Supper, Jesus mysteriously announces that one of his 12 closest followers will betray him. All deny it, but Jesus seems to know Judas is the one. That night, praying in a remote garden, Jesus is approached by an armed crowd sent by his enemies and led by Judas.
