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.
Judas Iscariot
According to the account in the Gospel of John, Judas carried the disciples' money bag or box (, "glōssokomon"), but John's Gospel makes no mention of the thirty pieces of silver as a fee for betrayal. The evangelist comments in John 12:5–6 that Judas spoke fine words about giving money to the poor, but the reality was "not that he cared for the poor, but [that] he was a thief, and had the money box; and he used to take what was put in it." However, in John 13:27–30, when Judas left the gathering of Jesus and his disciples with betrayal in mind, some [of the disciples] thought that Judas might have been leaving to buy supplies or on a charitable errand.
