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.
Mark 14
Judas then leaves and goes to the priests and gives up Jesus. The priests are so grateful that they pay Judas for his service. According to Matthew the payment was thirty silver coins. Mark then says that Judas looked for the right time to betray Jesus.
