Judas Iscariot was the son of Simon Iscariot and Cyborea (John 6:71 and 13:26). The Bible relates that Judas Iscariot was one of the disciples of Jesus Christ and betrayed him for 30 "pieces of silver" (most likely Tyrian shekels) to soldiers of the High Priest Caiphas, who then turned Jesus over to Pontius Pilate's soldiers.
The Gospel of Matthew says that after Jesus' arrest by the Roman authorities (but before his execution), Judas, overtaken by guilt returned the money to the priests that gave it to him and committed suicide by hanging himself.
According to John 13:29, Judas was the money keeper for Jesus and the Twelve Disciples.
The Acts of the Apostles states that Judas used the money to buy a field and fell down and burst apart. The field was then named Akeldama or the Field of Blood. Acts 1 goes on to describe how his place among the apostles was filled by Matthias.
A translation of a Gnostic document known as The Gospel of Judas has recently been made public, giving rise to much religious and historical discussion, but appears to be dated much later than the Judas' death.
