Both Luke and Mark describe Barabbas as having been imprisoned for insurrection and murder:
Luke 23:19 - (Barab′bas), a man who had been thrown into prison for an insurrection started in the city, and for murder.
Mark 15:7 - Among the rebels in prison, who had committed murder in the insurrection, there was a man called Barab′bas.
In these chapters we are also told that the crowd called for Barabbas' release, which was granted. Later, at Golgotha, Jesus is crucified with two "thieves" or "robbers." The Greek is λῃστής ( lestes). The word is related to "plunder."
This raises the question of whether these two men were merely "thieves" or actually radical Zealots who had joined the insurrection in which Barabbas is reported to have been involved. Such a scenario seems to be consistent with the fact that they had been convicted of a capital crime which may not have been the case (?) with mere robbery. It also dovetails with the Gospels' saying that there numerous persons arrested with Barabbas for insurrection.
So should we think of the two "thieves" who were crucified with Jesus as plunderer-insurrectionists, possibly even disciples of Barabbas? Please feel free to address translation issues as well as the social/legal context of their alleged crime.
