Judas Iscariot
There are several explanations as to why Judas betrayed Jesus. In the earliest account, in the Gospel of Mark, when he goes to the chief priests to betray Jesus, he is offered money as a reward, but it is not clear that money is his motivation. In the Gospel of Matthew account, on the other hand, he asks what they will pay him for handing Jesus over. In the Gospel of Luke and the Gospel of John, the devil enters into Judas, causing him to offer to betray Jesus. The Gospel of John account has Judas complaining that money has been spent on expensive perfumes to anoint Jesus which could have been spent on the poor, but adds that he was the keeper of the apostles' purse and used to steal from it.
The Passion of the Christ
Judas Iscariot, another of Jesus' disciples, having received a bribe of 30 pieces of silver, leads a group of temple guards to the forest and betrays Jesus' identity. As the guards arrest Jesus, a fight erupts wherein Peter draws his dagger and slashes the ear of Malchus, one of the guards and a servant of the high priest Caiaphas. Jesus heals Malchus' injury while reprimanding Peter. As the disciples flee, the guards secure Jesus, and beat him during the journey to the Sanhedrin.
