[The sacrificing of the mock king] It has been plausibly suggested that the addition Jesus is due to a scribe's reduplication, such as is common in Greek manuscripts, of the last syllable of the word humin = unto you. The in in uncials is a regular compendium for Iesun Jesus. In this way the name Jesus may have crept in before Barabbas. The entire story of Barabbas being released has an apocryphal air, for Pilate would not have let off a rebel against the Roman rule to please the Jewish mob; and the episode presupposes that it was the Sanhedrin which had condemned Jesus to death, which is equally improbable. What is probable, however, is that the Syrian soldiery to whom Pilate committed Jesus for crucifixion were accustomed to the Sacæa festival of Babylonian origin, and perhaps to the analogous Roman feast of the Saturnalia. In such celebrations a mock king was chosen, and vested with the costume, pomp, and privileges of kingship perhaps for as long as three days. Then the mimicry of slaying him was gone through, and sometimes the mock king was really put to death. Among Syrians the name Barabbas may--it is a mere hypothesis--have been the conventional appellation of the victim slain actually or in mock show on such occasions; and the soldiers of Pilate may have treated him en Barabbas. Loisy suggests in his Commentary on the Synoptics that this was the genesis of the Barabbas story. That a pagan soldiery treated Jesus as a mock king, when they dressed him in purple and set a crown of thorns on his head, and, kneeling before him, cried "Hail King of the Jews," is quite possible; and serious scholars like Paul Wendland (Hermes, Vol. XXXIII (1898), fol. 175) and Mr. W. R. Paton long ago discerned the probability.
But it was one thing for Syrians and pagans to envisage the crucifixion of Jesus under the aspect of a sacrifice to Molech, quite another thing for Jews--whether as his enemies or as his partisans--to do so; nor does the Gospel narrative suggest that any Jews took part in the ceremony. Perhaps it was out of respect for Jewish susceptibilities--and they were not likely to favour any mockery of their Messianic aspirations--that Pilate caused Jesus to be divested of the purple insignia of royalty and clad in his usual garb before he was led out of the guardroom and through the streets of Jerusalem on his way to Golgotha.
