But the nation of the Samaritans did not escape without tumults. The man who excited them to it was one who thought lying a thing of little consequence, and who contrived every thing so that the multitude might be pleased; so he bid them to get together upon Mount Gerizzim, which is by them looked upon as the most holy of all mountains, and assured them, that when they were come thither, he would show them those sacred vessels which were laid under that place, because Moses put them there. So they came thither armed, and thought the discourse of the man probable; and as they abode at a certain village, which was called Tirathaba, they got the rest together to them, and desired to go up the mountain in a great multitude together; but Pilate prevented their going up, by seizing upon file roads with a great band of horsemen and foot-men, who fell upon those that were gotten together in the village; and when it came to an action, some of them they slew, and others of them they put to flight, and took a great many alive, the principal of which, and also the most potent of those that fled away, Pilate ordered to be slain. …]
…] Now it came to pass, while Fadus was procurator of Judea, that a certain magician, whose name was Theudas, persuaded a great part of the people to take their effects with them, and follow him to the river Jordan; for he told them he was a prophet, and that he would, by his own command, divide the river, and afford them an easy passage over it; and many were deluded by his words. However, Fadus did not permit them to make any advantage of his wild attempt, but sent a troop of horsemen out against them; who, falling upon them unexpectedly, slew many of them, and took many of them alive. They also took Theudas alive, and cut off his head, and carried it to Jerusalem. This was what befell the Jews in the time of Cuspius Fadus’s government. …]
…] And now these impostors and deceivers persuaded the multitude to follow them into the wilderness, and pretended that they would exhibit manifest wonders and signs, that should be performed by the providence of God. And many that were prevailed on by them suffered the punishments of their folly; for Felix brought them back, and then punished them. Moreover, there came out of Egypt about this time to Jerusalem one that said he was a prophet, and advised the multitude of the common people to go along with him to the Mount of Olives, as it was called, which lay over against the city, and at the distance of five furlongs. He said further, that he would show them from hence how, at his command, the walls of Jerusalem would fall down; and he promised them that he would procure them an entrance into the city through those walls, when they were fallen down. Now when Felix was informed of these things, he ordered his soldiers to take their weapons, and came against them with a great number of horsemen and footmen from Jerusalem, and attacked the Egyptian and the people that were with him. He also slew four hundred of them, and took two hundred alive. But the Egyptian himself escaped out of the fight, but did not appear any more.
…] So Festus sent forces, both horsemen and footmen, to fall upon those that had been seduced by a certain impostor, who promised them deliverance and freedom from the miseries they were under, if they would but follow him as far as the wilderness. Accordingly, those forces that were sent destroyed both him that had deluded them, and those that were his followers also.
The authorities clearly understood that Jesus was not leading an armed rebellion, otherwise the disciples would have been arrested too, or as we can see from the above examples, worse. They however thought that He had the potential to stir up the populace (I mean, preaching about the Kingdom of God within the Empire of Caesar? Staging a ‘public demonstration’ in Jerusalem upon entry?) so they ‘nipped the bud’ before it escalated.
