But while such men went out into the world and brought back wealth of one kind or another to Palestine, other Jews were content to make their homes in foreign parts. At Alexandria in particular Alexander provided for a Jewish colony which soon became Hellenic enough in speech to require a translation of the Law. It is probable that, as in Palestine an Aramaic paraphrase of the Hebrew text was found to be necessary, so in Alexandria the Septuagint grew up gradually, as need arose. The legendary tradition which even Philo accepts gives it a formal nativity, a royal patron and inspired authors. From the text which Philo uses, it is probable that the translation had been transmitted in writing; and his legend probably fixes the date of the commencement of the undertaking for the reign of Ptolemy Lagus. The apology for the necessary defects of a translation put forward by the translator of _Ecclesiasticus_ in his Prologue shows that the work was carried on beyond the limits of the Law. Apparently it was in progress at the time of his coming to Egypt in the reign of Ptolemy Euergetes I. or II. He seems to regard this body of literature as the answer to the charge that the Jews had contributed nothing useful for human life. Once translated into Greek, the Scriptures became a bond of union for the Jews of the dispersion and were at least capable of being used as an instrument for the conversion of the world to Judaism. So far as the latter function is concerned Philo confesses that the Law in his day shared the obscurity of the people, and seems to imply that the proselytes adopted little more than the monotheistic principle and the observance of the Sabbath. According to Juvenal the sons of such proselytes were apt to go farther and to substitute the Jewish Law for the Roman-- Romanas autem soliti contemnere leges; Judaicum ediscunt et servant ac metuunt ius Tradidit arcano quodcunque volumine Moyses.
