Judas Iscariot
Judas Iscariot (died AD) was a disciple and one of the original Twelve Disciples of Jesus Christ. According to all four canonical gospels, Judas betrayed Jesus to the Sanhedrin in the Garden of Gethsemane by kissing him and addressing him as "Rabbi" to reveal his identity to the crowd who had come to arrest him. His name is often used synonymously with betrayal or treason. Judas's epithet "Iscariot" most likely means he came from the village of Kerioth, but this explanation is not universally accepted and many other possibilities have been suggested.
Jesus Christ Superstar
At what Jesus knows will be the Last Supper, he pours wine and passes bread for his apostles ("The Last Supper"). Very aware of the ordeal he faces, he is stung when the others pay little attention to him; "For all you care this wine could be my blood / For all you care this bread could be my body," he remarks, alluding to (and anticipating) the Christian doctrine of the Eucharist. He asks them to remember him when they eat and drink; he predicts that Peter will deny him three times "in just a few hours" and that one of them will betray him. Judas, believing that Jesus already knows ("cut the dramatics, you know very well who"), admits he is the one and angrily accuses Jesus of acting recklessly and egotistically. Claiming he does not understand Jesus's decisions, he leaves to bring the Roman soldiers.
