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 Wandering Jew (novel)
With François Hardy, Rodin shows him how Hardy's best friend had betrayed him. He also arranges for Hardy's mistress to leave for the Americas, and has Hardy's treasured factory burn to the ground (all this on the same day). Hardy takes refuge among the Jesuits, who persuade him to enter their order.
