Thanks to his copious sources, he is able to give a detailed account of the relation of the Jews to Julius Caesar and of the decrees which were made in their favor at his instance. It has been conjectured with much probability that Josephus obtained his series of documents from Nicholas, who had collected them for the purpose of defending the Jews of Asia Minor in the inquiry which Marcus Agrippa conducted during the reign of Herod.[1] He says that he will set down the decrees that are treasured in the public places of the cities, and those which are still extant in the Capitol of Rome, "so that all the rest of mankind may know what regard the kings of Asia and Europe have had for the Jewish people." In a subsequent book, when he is recounting the events of Herod's reign,[2] Josephus sets forth a further series of decrees in favor of the Jews, issued by Caesar Augustus and his lieutenant Marcus Agrippa. These likewise he probably derived from Nicholas, who was the court advocate and court chronicler at the time they were promulgated. But he enlarges on his motive for giving them at length, pointing to them with pride as a proof of the high respect in which the Jews were held by the heads of the Roman Empire before the disaster of the war. Though in his own day they were fallen to a low estate, at one time they had enjoyed special favor: "And I frequently mention these decrees in order to reconcile other peoples to us and to take away the causes of that hatred which unreasonable men bear us. As for our customs, he continues, each nation has its own, and in almost every city we meet with differences; but natural justice is most agreeable to the advantage of all men equally, and to this our laws have the greatest regard, and thereby render us benevolent and friendly to all men, so that we may expect the like return from others, and we may remind them that they should not esteem difference of institutions a sufficient cause of alienation, but join with us in the pursuit of virtue and righteousness, for this belongs to all men in common."[3] [Footnote 1: Comp.
