7. For our forefathers did not only appoint the best of these priests, and those that attended upon the Divine worship, for that design from the beginning, but made provision that the stock of the priests should continue unmixed and pure; for he who is partaker of the priesthood must propagate of a wife of the same nation, without having any regard to money, or any other dignities; but he is to make a scrutiny, and take his wife's genealogy from the ancient tables, and procure many witnesses to it. (7) And this is our practice not only in Judea, but wheresoever any body of men of our nation do live; and even there an exact catalogue of our priests' marriages is kept; I mean at Egypt and at Babylon, or in any other place of the rest of the habitable earth, whithersoever our priests are scattered; for they send to Jerusalem the ancient names of their parents in writing, as well as those of their remoter ancestors, and signify who are the witnesses also. But if any war falls out, such as have fallen out a great many of them already, when Antiochus Epiphanes made an invasion upon our country, as also when Pompey the Great and Quintilius Varus did so also, and principally in the wars that have happened in our own times, those priests that survive them compose new tables of genealogy out of the old records, and examine the circumstances of the women that remain;for still they do not admit of those that have been captives, as suspecting that they had conversation with some foreigners. But what is the strongest argument of our exact management in this matter is what I am now going to say, that we have the names of our high priests from father to son set down in our records for the interval of two thousand years; and if any of these have been transgressors of these rules, they are prohibited to present themselves at the altar, or to be partakers of any other of our purifications; and this is justly, or rather necessarily done, because every one is not permitted of his own accord to be a writer, nor is there any disagreement in what is written; they being only prophets that have written the original and earliest accounts of things as they learned them of God himself by inspiration; and others have written what hath happened in their own times, and that in a very distinct manner also.
8. For we have not an innumerable multitude of books among us, disagreeing from and contradicting one another, [as the Greeks have,] but only twenty-two books, (8) which contain the records of all the past times; which are justly believed to be divine;and of them five belong to Moses, which contain his laws and the traditions of the origin of mankind till his death. This interval of time was little short of three thousand years; but as to the time from the death of Moses till the reign of Artaxerxes king of Persia, who reigned after Xerxes, the prophets, who were after Moses, wrote down what was done in their times in thirteen books.
The remaining four books contain hymns to God, and precepts for the conduct of human life. It is true, our history hath been written since Artaxerxes very particularly, but hath not been esteemed of the like authority with the former by our forefathers, because there hath not been an exact succession of prophets since that time; and how firmly we have given credit to these books of our own nation is evident by what we do; for during so many ages as have already passed, no one has been so bold as either to add any thing to them, to take any thing from them, or to make any change in them; but it is become natural to all Jews immediately, and from their very birth, to esteem these books to contain Divine doctrines, and to persist in them, and, if occasion be willingly to die for them. For it is no new thing for our captives, many of them in number, and frequently in time, to be seen to endure racks and deaths of all kinds upon the theatres, that they may not be obliged to say one word against our laws and the records that contain them; whereas there are none at all among the Greeks who would undergo the least harm on that account, no, nor in case all the writings that are among them were to be destroyed; for they take them to be such discourses as are framed agreeably to the inclinations of those that write them; and they have justly the same opinion of the ancient writers, since they see some of the present generation bold enough to write about such affairs, wherein they were not present, nor had concern enough to inform themselves about them from those that knew them; examples of which may be had in this late war of ours, where some persons have written histories, and published them, without having been in the places concerned, or having been near them when the actions were done; but these men put a few things together by hearsay, and insolently abuse the world, and call these writings by the name of Histories.
