According to the Bible Judas Iscariot was one of the disciples of Jesus Christ. Judas was the disciple that betrayed Jesus 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 may have kept the money for Jesus and the Twelve Disciples.
The Acts of the Apostles states however that Judas used the money to buy a field but apparently 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.
