To prove that these dicta were actually uttered by the Men of the Great Synagogue is impossible. But it is admitted that they are very ancient; and the tradition which places them at the forefront of the development of Rabbinism has this much in its favour, that they logically belong there. Either they date from a time not remote from Ezra, or they express the opinion of some later teacher as to the aims and methods of those who in that early time were responsible for the training of the people in the religion of Torah. This latter interpretation is possible; but the form in which the brief statement is made clearly shows that the Rabbis who compiled the Mishnah had no suspicion that the dicta in question were the utterances of a later teacher. If they had had such a thought they would have expressed it thus: "Rabbi so-and-so said that the Men of the Great Synagogue had said, etc." There is no hint that the three maxims are anything else but an old tradition; and the fact that these and no more are ascribed to the Men of the Great Synagogue indicates, by its very moderation, some reason for so ascribing them. A capricious inventor would have attributed much more to so ancient an authority, in order to obtain for his inventions the sanction of high antiquity. There is really nothing improbable in the transmission, even from the time of Ezra, of these bare fragments of ancient teaching. Their contents are in keeping with this supposition; and, if they were a later invention, they nevertheless accurately describe what the men of Ezra's time must chiefly have had at heart. They are instructions to do certain things, and are addressed to persons who had some special responsibility in reference to the Torah. We have seen that the central idea of Ezra's reformation was to make the Torah the inspiring and controlling influence in Jewish life, both national and individual. To this end it was needful that the people should be taught, that they might know what was in the Torah, _i.e._ what God had given for their instruction; also that they should be able to appeal to competent authority for the settlement of doubtful points. The Torah was the source of divine truth and divine justice, and both must be made accessible to those whose life as a conscious service of God depended on them. The shrine in which the divine treasure was contained must be kept safe from injury, as if it were protected by a fence.
