 CHAPTER 1. 

 HOW CYRENIUS WAS SENT BY CAESAR TO MAKE A TAXATION OF SYRIA AND JUDEA; AND HOW COPONIUS WAS SENT TO BE PROCURATOR OF JUDEA; CONCERNING JUDAS OF GALILEE AND CONCERNING THE SECTS THAT WERE AMONG THE JEWS.  

 "1. ...Moreover, Cyrenius came himself into Judea, which was now added to the province of Syria, to take an account of their substance, and to dispose of Archelaus's money; but the Jews, although at the beginning they took the report of a taxation heinously, yet did they leave off any further opposition to it, by the persuasion of Joazar, who was the son of Beethus, and high priest; so they, being over-pesuaded by Joazar's words, gave an account of their estates, without any dispute about it. Yet was there one Judas, a Gaulonite, (1) of a city whose name was Gamala, who, taking with him Sadduc, (2) a Pharisee, became zealous to draw them to a revolt, who both said that this taxation was no better than an introduction to slavery, and exhorted the nation to assert their liberty; as if they could procure them happiness and security for what they possessed, and an assured enjoyment of a still greater good, which was that of the honor and glory they would thereby acquire for magnanimity. They also said that God would not otherwise be assisting to them, than upon their joining with one another in such councils as might be successful, and for their own advantage; and this especially, if they would set about great exploits, and not grow weary in executing the same; so men received what they said with pleasure, and this bold attempt proceeded to a great height. All sorts of misfortunes also sprang from these men, and the nation was infected with this doctrine to an incredible degree; one violent war came upon us after another, and we lost our friends which used to alleviate our pains; there were also very great robberies and murder of our principal men. This was done in pretense indeed for the public welfare, but in reality for the hopes of gain to themselves; whence arose seditions, and from them murders of men, which sometimes fell on those of their own people, (by the madness of these men towards one another, while their desire was that none of the adverse party might be left,) and sometimes on their enemies; a famine also coming upon us, reduced us to the last degree of despair, as did also the taking and demolishing of cities; nay, the sedition at last increased so high, that the very temple of God was burnt down by their enemies' fire. Such were the consequences of this, that the customs of our fathers were altered, and such a change was made, as added a mighty weight toward bringing all to destruction, which these men occasioned by their thus conspiring together; for Judas and Sadduc, who excited a fourth philosophic sect among us, and had a great many followers therein, filled our civil government with tumults at present, and laid the foundations of our future miseries, by this system of philosophy, which we were before unacquainted withal, concerning which I will discourse a little, and this the rather because the infection which spread thence among the younger sort, who were zealous for it, brought the public to destruction. 

 2. The Jews had for a great while had three sects of philosophy peculiar to themselves; the sect of the Essens, and the sect of the Sadducees, and the third sort of opinions was that of those called Pharisees; of which sects, although I have already spoken in the second book of the Jewish War, yet will I a little touch upon them now." 

 In conclusion, Josephus says there are three sects, Essenes, Sadducees, and Pharisees, plus a fourth sect, founded by Judas of Gamala (in Galilee) and Sadduc the Pharisee in 6ce, later called Zealots. 

 Thus the claim that the 2nd Temple Pharisees were relatively apolitical is very misleading. No doubt Hillel was relatively apolitical, but Shammai? Obviously Sadduc the Pharisee was relatively political.
