judas iscariot

In Christianity, Judas Iscariot was one of the original Twelve Apostles of Jesus Christ. Judas betrayed Jesus to the Sanhedrin in the Garden of Gethsemane, in exchange for thirty pieces of silver, by kissing him on the cheek and addressing him as "master" to reveal his identity in the darkness to the crowd who had come to arrest him.

In modern times, his name is often used synonymously with betrayal or treason.
