fundamental principles of the national religion. This again simply means that the Mosaism of Ezra or Nehemiah must have differed essentially from the priestly teaching prior to their arrival. The arguments of conservative writers involve concessions which, though often overlooked by their readers, are very detrimental to the position they endeavour to support, and the objections they bring against the theory of the introduction of new law-books (under a Josiah or an Ezra) apply with equal force to the promulgation of Mosaic teaching which had been admittedly ignored or forgotten. Their arguments have most weight, however, when they show the hazardous character of reconstructions which rely upon the trustworthiness of the historical narratives. What book Ezra really brought from Babylon is uncertain; the writer, it seems, is merely narrating the introduction of the Law ascribed to Moses, even as a predecessor has recounted the discovery of the Book of the Law, the Deuteronomic code subsequently included in the Pentateuch. The importance which the biblical writers attach to the return from Babylon in the reign of Artaxerxes forms a starting-point for several interesting inquiries. Thus, in any estimate of the influence of Babylonia upon the Old Testament, it is obviously necessary to ask whether certain features (a) are of true Babylonian origin, or (b) merely find parallels or analogies in its stores of literature; whether the indebtedness goes back to very early times or to the age of the Assyrian domination or to the exiles who now returned. Again, there were priestly and other families--some originally of "southern" origin--already settled around Jerusalem, and questions inevitably arise concerning their relation to the new-comers and the literary vicissitudes which gave us the Old Testament in its present form. To this age we may ascribe the literature of the Priestly writers (symbolized by P), which differs markedly from the other sources. Yet it is clear from the book of Genesis alone that in the age of Priestly writers and compilers there were other phases of thought. Popular stories with many features of popular religion were current. They could be, and indeed had been made more edifying; but the very noteworthy conservatism of even the last compiler or editor, in contrast to the re-shaping and re-writing of the material in the book of Jubilees, indicates that the Priestly spirit was not that of the whole community. But through the Priestly hands the Old Testament history passed, and their standpoint colours its records. This is especially true of the history of the exilic and post-exilic periods, where the effort is made to preserve the continuity of Israel and the Israelite community (Chronicles--Ezra--Nehemiah). The bitterness aroused by the ardent and to some extent unjust zeal of the reforming element can only be conjectured.
