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.
Twelfth Apostle
Another interesting aspect is the title. The "twelfth apostle" of Jesus Christ was Judas, the traitor. What all this means (and there have been many speculations) is impossible to know, but the title track definitely references religious imagery. "They say you’re the one to rely on all the days/ they say you died before/ and you’re smiling now/Well I would like to know you." But by song's end salvation has not been received, with the singer moaning "where are you going/come back again." Is this a man who cannot be "saved?" Hard to know, but an interesting twist.
