Now as Josephus was thus engaged in the administration of the affairs of Galilee, there arose a treacherous person, a man of Gischala, the son of Levi, "whose name was John. His character was that of a very cunning and very knavish person, beyond the ordinary rate of the other men of eminence there, and for wicked practices he had not his fellow any where.
He was a ready liar, and yet very sharp in gaining credit to his fictions: he thought it a point of virtue to delude people, and would delude even such as were the dearest to him. He was a hypocritical pretender to humanity, but where he had hopes of gain, he spared not the shedding of blood: his desires were ever carried to great things, and he encouraged his hopes from those mean wicked tricks which he was the author of.
It was John, the son of a certain man whose name was Levi, that drew them into this rebellion, and encouraged them in it.
Now this was the work of God, who therefore preserved this John, that he might bring on the destruction of Jerusalem;
But for John, he was very little concerned for those whom he had left behind him, but went about among all the people, and persuaded them to go to war, by the hopes he gave them. He affirmed that the affairs of the Romans were in a weak condition, and extolled his own power.
Now it was John who, as we told you, ran away from Gischala, and was the occasion of all these being destroyed. He was a man of great craft, and bore about him in his soul a strong passion after tyranny
But John held the temple
[MY NOTE: When the leaders of the other two seditious factions rose against him, John of Gischala moved his forces into the temple and conducted war against the other factions from there, wantonly killing any who came under their fire with no regard for either priests or innocents. John held the temple throughout most of the civil war inside Jerusalem, and the war with Rome outside of it.]
But as for John, when he could no longer plunder the people, he betook himself to sacrilege, and melted down many of the sacred utensils, which had been given to the temple; as also many of those vessels which were necessary for such as ministered about holy things, the caldrons, the dishes, and the tables; nay, he did not abstain from those pouring vessels that were sent them by Augustus and his wife; for the Roman emperors did ever both honor and adorn this temple; whereas this man, who was a Jew, seized upon what were the donations of foreigners, and said to those that were with him, that it was proper for them to use Divine things, while they were fighting for the Divinity, without fear, and that such whose warfare is for the temple should live of the temple; on which account he emptied the vessels of that sacred wine and oil, which the priests kept to be poured on the burnt-offerings, and which lay in the inner court of the temple, and distributed it among the multitude, who, in their anointing themselves and drinking, used [each of them] above an hin of them.
And here I cannot but speak my mind, and what the concern I am under dictates to me, and it is this: I suppose, that had the Romans made any longer delay in coming against these villains, that the city would either have been swallowed up by the ground opening upon them, or been overflowed by water, or else been destroyed by such thunder as the country of Sodom perished by, for it had brought forth a generation of men much more atheistical than were those that suffered such punishments; for by their madness it was that all the people came to be destroyed.
Yet did John demonstrate by his actions that these Sicarii [assassins] were more moderate than he was himself, for he not only slew all such as gave him good counsel to do what was right, but treated them worst of all, as the most bitter enemies that he had among all the Citizens; nay, he filled his entire country with ten thousand instances of wickedness, such as a man who was already hardened sufficiently in his impiety towards God would naturally do; for the food was unlawful that was set upon his table, and he rejected those purifications that the law of his country had ordained; so that it was no longer a wonder if he, who was so mad in his impiety towards God, did not observe any rules of gentleness and common affection towards men.
