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.
Burning of Judas
In many parts of Latin America this practice occurs on the eve of the new year as a symbol of ridding one's self of evil and beginning a new year in spiritual purity. Some communities observe this ritual using various effigies, including the biblical Judas (who betrayed Jesus). This custom, during which the effigy is burned on a stake, is called "Quema del Judas" ("the burning of Judas") in Uruguay and Argentina, and "Quema del Año Viejo" ("the burning of the old year.") in other places.
