Not all Jews!! The Jewish religious order opposed the War started by the zealots. It was all about money and power for them which they derived from their unholy alliance with Rome. They worshiped and declared Caesar as their one and only true king as we see here.
John 19: 12, 15 From this [time] was Pilate seeking to release him, and the Jews were crying out, saying, `If this one thou mayest release, thou art not a friend of Caesar; every one making himself a king, doth speak against Caesar.' ...and they cried out, `Take away, take away, crucify him;' Pilate saith to them, `Your king shall I crucify?' the chief priests answered, `We have no king except Caesar. (YLT)
Jesus was crucified more over power and money than any charge of blasphemy. Christ was betrayed over money and He was killed over money. If Christ were ever made "King of the Jews" He would have stripped these wicked priests of their wealth and power just as He did when He turned over the tables of the money changers. Jerusalem derived its wealth from its temple tax which was 10% of all Jewish income, not just in Israel but from Jews all over the world. Both Tacitus and Titus declared that Jerusalem was the richest city in the world, superior to even Rome's wealth. Tacitus writes, “Their capital is Jerusalem. Here stood their Temple with its boundless riches.” Because of this incredible amount of money funneling into Jerusalem through the Temple, first-century Jerusalem was the wealthiest city in the Roman world per capita. Before the Romans went on a killing spree in the city, Caesar Titus is recorded to have said the following implying the fact that Jerusalem was the richest city in the Roman Empire: “We [the Romans] have given you leave to gather up that tribute which is paid to God . . . till at length you became richer than we ourselves[.]” The religious order "worshiped" money over God.
Here one can see that it was the worship of money (which not ironically contained the deified image of Caesar, the beast) that ultimately caused Jesus and His followers to be persecuted and killed by the Jewish civil and religious authorities. This is why the Bible says “[T]he love of money is the root of all evil (1 Timothy 6:10).” It was greed that was Israel’s ultimate spiritual sin. And it was this greed that motivated these unjust murders. James 2:6, 5:1-6 and Luke 16:19-31 echo this link. After admonishing the church for showing favoritism to rich parishioners, James says the following in James 2:6: “Is it not the rich who are exploiting you? Are they not the ones who are dragging you into court?” Furthermore, after crying “woe” to those who have stored up wealth in the last days in James 5:1-6, James says the following in the next verse: “You [the rich] have condemned and murdered the innocent one, who was not opposing you (James 5:6).” The “innocent one” murdered by the rich was Jesus. James could not be more explicit that it was the rich who were persecuting the church. If the rich were the enemies of the saints because they were the ones actively persecuting Jesus and His people, is it any wonder that the tangible aspect of the mark of the beast is money? The mark is both spiritual and tangible.
Roman coins from the time of Augustus to Domitian contained the graven image of Caesar often with claim of deity on the reverse side of the coin. All money and deeds of purchase were marked with Caesar’s name and/or image hence no one could buy or sell unless he had the mark of the beast (Roman Money). We can't buy or sell today without money either. But, per the Law of Moses, Jews were forbidden to possess money bearing the graven image of a false god. These coins would be considered little idols. Thus the Jews were allowed to mint their own currency without the image of Caesar. Handling Roman money alone was not a crime, but the love or worship of such money was. Most Jews of the first century living in Israel used Jewish coins. However, we know that Roman money was also in circulation. We know from Mat 22:15-21 that the Pharisees used Roman currency when they produced a Roman coin for Jesus. These same Pharisees not only had the mark spiritual, they possessed it literally.
The Jewish religious order of the day swore their allegiance to Caesar as I demonstrated. They trusted in Rome to protect them in exchange for keeping the Jews in line. The zealots threatened their way of life and thus they opposed the war with Rome. When Titus broke through all the priests left alive were brought before him and he ordered them all to be killed.
It would take me several pages to fully explain this so let this sink in for now....
