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 predicts his betrayal
The attribution of the title Rabbi to Jesus by the Iscariot in this episode is unique to him, for one after another the other Apostles say "Surely it is not I, Lord", using the Lord (Kyrios) title. The Iscariot again calls Jesus Rabbi in when he betrays him to the Sanhedrin in the Kiss of Judas episode.
