To the latest editor of the early narratives we owe the preservation of some or the oldest and most valuable sections of the Old Testament. In that age and land of perishable writing materials, the prevailing method of compilation was one of the effective means whereby the important portions of primitive records were handed down in practically their original form. It is well that we are beginning to understand its significance in the realization of the divine purpose. Important beyond words, although often overlooked, were the services of the faithful editors who without the slightest desire for personal glory or reward, other than the perpetuation of truth, carefully selected, condensed, and combined material gleaned from earlier and fuller sources. To them is due the marvellous preservation of our Old Testament, To the honored rôle of the prophets and apostles, therefore, let us add the anonymous redactors. [Sidenote: _Date of the beginning of the cannonization of the Law_] The final editors were the immediate precursors of those who formed the successive canons of the Old Testament. Indeed, between the work of the former and the latter there is no clear line of demarcation. A period shortly after 400 B. c. is the date usually accepted for the work of the final editor of the Pentateuch; the canonization of the law, which included these five books, is dated between 400 and 300 B.C. The real canonization of Israel's laws had, however, begun much earlier. The primitive decalogue, represented by Exodus xxxiv., and probably from the first associated with Moses, appears, in the earliest periods of Israel's history, to have enjoyed a canonical authority. The primitive accounts, in Exodus xix., of the establishment of the covenant by Jehovah with his people mark the real beginning of the process of canonization,--a process, that is, of attributing to certain laws a unique and commanding authority. [Sidenote: _Popular acceptance and promulgation of the earlier codes_] Likewise the successive civil, humane, and ceremonial decalogues appear from the days of the united kingdom to have occupied a similar position. Primarily this was probably due to the fact that each was based upon a divine _torah_ or decision, received from Jehovah through the priestly oracle. The public reading and promulgation of the Deuteronomic laws in the days of Josiah, with the attestation of the prophets and the solemn adoption by the people, was an act of canonization far more formal than the final acceptance of the New Testament writings by the Council of Carthage.
