Before the completion of the canon of the Old Testament the language of the Jews began to exhibit evidences of change, and through their intercourse with the various peoples of Mesopotamia (or Aram) the later books show a distinct tendency towards Aramaic forms and idioms. This tendency, already apparent at the time of the return from the Captivity, was accelerated by the political events which followed. During the hundred and eighty years and more which intervened between the Restoration of the Temple, B.C. 516, and the overthrow of Darius Codomannus, B.C. 331, Judæa was a portion of that province of the Persian empire, in which the Aramaic was the prevalent dialect. The ancient Hebrew gradually ceased to be the language of the Jews in common life, and, before the time of our Lord, had been supplanted by the language of their Eastern neighbours. With the decline of the Hebrew language there arose amongst the Jews the class of men known as Scribes, whose primary function was that of preparing copies of the Scriptures, and of guarding the sacred text from the intrusion of errors. Owing to their great zeal for the preservation of the letter of Scripture, and to their natural tendency to hold fast to the honour and influence which their special knowledge and skill gave to them, they did not, when Hebrew ceased to be intelligible to the common people, set themselves to the task of giving them the Bible in a form which they could understand; but, magnifying their office overmuch, assumed the position of authoritative teachers and expounders of the Law. Scholars might still study for themselves the ancient Bible, but for the people at large the form which the Scriptures now practically assumed was that of the spoken utterances of the Scribes. How imperfect and unsatisfactory this must have been is obvious; and the more so as these teachers did not content themselves with simply rendering the ancient text into a familiar form, but intermingled with it a mass of human traditions that obscured and sometimes contradicted its meaning. It would have been a great gain for the people of Judæa if their regard for the outward form of their Scriptures had been less extreme and more enlightened, and if competent men amongst them had ventured so to revise the ancient books that their fellow countrymen might read in their own tongue the wonderful works and words of God.
