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.
Sanhedrin trial of Jesus
Jesus is generally quiet, does not mount a defense, and rarely responds to the accusations, but is condemned by the Jewish authorities for various accusations, violating the Sabbath law(by healing on the Sabbath), threatening to destroy the Jewish Temple, sorcery, exorcising people by the power of demons and claiming to be both the Messiah and the Son of God. The Jewish leaders then take Jesus to Pontius Pilate, the governor of Roman Judaea, and ask that he be tried for claiming to be the King of the Jews.
