Wait, what? Was there another Jesus that I don't know about? And who was Ananus?
Let me set the scene for you.
John of Gischala, who has led the people of his town into rebellion against Rome, is besieged in Gischala by Titus and his legions. John strikes a deal with Titus, asking him to pull his troops back for the city's Sabbath observances. Titus agrees, and in the dark of that night, John, several thousand of his men, along with their wives and children, sneak out of the city and head for the safety of Jerusalem.
When morning breaks, Titus learns John has fled the city because the people of Gischala - who want no part of war with Rome - invite Titus and his troops in as a liberator with "great acclamations of joy."
Titus orders his men to hunt down John and the men who fled with him.
In the meantime, John is setting a pace for Jerusalem that he knows the women and children of his "escapees" can't sustain, and when John learns the Romans are pursuing him, he and his men flee even faster, leaving the women and children behind. Those that are not rounded up by the Romans or killed by them are lost in the wilderness between Galilee and Jerusalem.
The Romans quit the pursuit realizing they can't catch him.
John then enters Jerusalem and tells the people there - who hunger for news of what's happening in the north - that the Romans are weak and that he had easily beaten them. They are encouraged by his boldness (and his lies) to take up arms to defend Jerusalem.
John and his men soon find, however, that they are not alone in their hunger for power over Jerusalem, and find competition from another faction of insurrectionists in the city led by a man named Eleazar. These two factions begin warring against each other and killing innocent bystanders and those they suspect of wanting peace with Rome.
John leads his men into the temple where they, though fewer in number, have a tactical advantage because of the towers they can occupy; shooting down at their enemies.
This is seen as an abomination to many of the priests, including high priests named Jesus, and Ananus, whom John had deceived into friendship with him. When Ananus learned that John had taken the temple as a fortress, he musters the ordinary citizens of Jerusalem to put down this "tyrant", who wantonly killed anyone who got in his way.
Ananus then learns that John had sent messengers to the Idumeans (Edomites) to get them to fight on his side in the civil war, and when the Idumeans approach Jerusalem, Ananus orders the gates be locked against them. Jesus, standing on the wall, tells them, "I see that you are come to support the vilest of men against us..."
He was not talking about the Romans as the "vilest of men" rather John of Gischala.
He continued:
But now for these men who have invited you, if you were to examine them one by one, every one of them would be found to have deserved ten thousand deaths; for the very rascality and offscouring of the whole country, who have spent in debauchery their own substance, and, by way of trial beforehand, have madly plundered the neighboring villages and cities, in the upshot of all, have privately run together into this holy city. They are robbers, who by their prodigious wickedness have profaned this most sacred floor, and who are to be now seen drinking themselves drunk in the sanctuary, and expending the spoils of those whom they have slaughtered upon their unsatiable bellies. Josephus.
Later that night, John and his men took saws from the temple (it was undergoing renovation) and cut open the bars that held the gates closed, letting the enraged Idumeans into the city. Here's how Josephus finished their story:
But the rage of the Idumeans was not satiated by these slaughters; but they now betook themselves to the city, and plundered every house, and slew every one they met; and for the other multitude, they esteemed it needless to go on with killing them, but they sought for the high priests, and the generality went with the greatest zeal against them; and as soon as they caught them they slew them, and then standing upon their dead bodies, in way of jest, upbraided Ananus with his kindness to the people, and Jesus with his speech made to them from the wall. Nay, they proceeded to that degree of impiety, as to cast away their dead bodies without burial, although the Jews used to take so much care of the burial of men, that they took down those that were condemned and crucified, and buried them before the going down of the sun.
I should not mistake if I said that the death of Ananus was the beginning of the destruction of the city, and that from this very day may be dated the overthrow of her wall, and the ruin of her affairs, whereon they saw their high priest, and the procurer of their preservation, slain in the midst of their city. He was on other accounts also a venerable, and a very just man; and besides the grandeur of that nobility, and dignity, and honor of which he was possessed, he had been a lover of a kind of parity, even with regard to the meanest of the people; he was a prodigious lover of liberty, and an admirer of a democracy in government; and did ever prefer the public welfare before his own advantage, and preferred peace above all things; for he was thoroughly sensible that the Romans were not to be conquered.
He also foresaw that of necessity a war would follow, and that unless the Jews made up matters with them very dexterously, they would be destroyed; to say all in a word, if Ananus had survived, they had certainly compounded matters; for he was a shrewd man in speaking and persuading the people, and had already gotten the mastery of those that opposed his designs, or were for the war. And the Jews had then put abundance of delays in the way of the Romans, if they had had such a general as he was.
Jesus was also joined with him; and although he was inferior to him upon the comparison, he was superior to the rest; and I cannot but think that it was because God had doomed this city to destruction, as a polluted city, and was resolved to purge his sanctuary by fire, that he cut off these their great defenders and well-wishers, while those that a little before had worn the sacred garments, and had presided over the public worship; and had been esteemed venerable by those that dwelt on the whole habitable earth when they came into our city, were cast out naked, and seen to be the food of dogs and wild beasts. And I cannot but imagine that virtue itself groaned at these men's case, and lamented that she was here so terribly conquered by wickedness. And this at last was the end of Ananus and Jesus.

Such was the legacy left by Ananus and Jesus.
