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.
Last Supper
In and , Judas is specifically identified as the traitor. In the Gospel of John, when asked about the traitor, Jesus states:
The three Synoptic Gospel accounts give somewhat different versions of the order of the meal. In chapter 26 of the Gospel of Matthew, Jesus prays thanks for the bread, divides it, and hands the pieces of bread to his disciples, saying "Take, eat, this is my body." Later in the meal Jesus takes a cup of wine, offers another prayer, and gives it to those present, saying "Drink from it, all of you; for this is my blood of the covenant, which is poured out for many for the forgiveness of sins. I tell you, I will never again drink of this fruit of the vine until that day when I drink it new with you in my Father’s kingdom."
