3. But, as light by its very nature illumines its surroundings, so the Torah in the possession of the Jewish people was certain to become the light of mankind. First of all, the book of Law itself insists that the father shall teach the word of God to his children, using many signs and ceremonies that they may meditate on the works of God and walk in the path of virtue, and that the divine commands should be “in the mouth and in the heart of all to do them.”(1144) It was made incumbent upon the high priest or king to read the Law at least once every seven years to the whole people assembled in the holy city for the autumnal festival,—men, women, children, and the sojourners in the gates,—so that it should become their common property.(1145) This precept probably gave rise to the triennial and later the annual system of Torah reading on the Sabbath. But in addition to the book of Law the prophetic words of consolation were read to the people, a custom which originated in the Babylonian exile, and was continued under the name of _Haftarah_ (“dismissal” of the congregation).(1146) The seer of the exile refers to these prophetic words of comfort which were offered to the people on the Sabbath as well as other feasts and fasts: “Attend unto Me, O My people, and give ear unto Me, O My nation, for instruction (Torah) shall go forth from Me, and My right on a sudden for a light of the people.... Hearken unto Me, ye that know righteousness, the people in whose heart is My law; fear ye not the taunt of men, neither be ye dismayed at their revilings. For the moth shall eat them up like a garment, and the worm shall eat them like wool; but My favor shall be forever, and My salvation unto all generations.”(1147) Moved by such stirring ideals, Synagogues arose in Jewish settlements all over the globe, and the book of the Law, in its vernacular versions, Greek and Aramaic, together with the words of the prophets, became the general source of instruction. In the words of the Psalms, it became “the testimony of the Lord, making wise the simple,” “rejoicing the heart,” “enlightening the eyes,” “more to be desired than gold.”(1148) Nay more, the study of the Law became the duty of every man, and he who failed to live up to the precepts of the devotees of the Law, the Pharisean fellowships, was scorned as belonging to the lower class, _am haaretz_. Every morning the pious Jew, first thanking God for the light of day, followed this up by thanking Him for the Torah, which illumines the path of life. “The welfare of society rests upon the study of the Law, divine service and organized charity,” was a saying of Simon the Just, a high priest of the beginning of the third pre-Christian century.(1149) Thus learning and teaching became leading occupations for the Jew, and the two main departments of Jewish literature, correspondingly, are _Torah_ and _Talmud_, that is, the written Law and its exposition. Indeed, the highest title which the rabbis could find for
