The literary and historical investigation on which we thus enter is both wide and difficult. It falls into three parts. In the first, which lays the foundations, the data relating to sacred archaeology are brought together and arranged in such a way as to show that in the Pentateuch the elements follow upon one another and from one another precisely as the steps of the development demonstrably do in the history. Almost involuntarily this argument has taken the shape of a sort of history of the ordinances of worship. Rude and colourless that history must be confessed to be,--a fault due to the materials, which hardly allow us to do more than mark the contrast between pre-exilic and post-exilic, and, in a secondary measure, that between Deuteronomic and pre-Deuteronomic. At the same time there is this advantage arising out of the breadth of the periods treated: they cannot fail to distinguish themselves from each other in a tangible manner; it must be possible in the case of historical, and even of legal works, to recognise whether they were written before or after the exile. The second part, in many respects dependent on the first, traces the influence of the successively prevailing ideas and tendencies upon the shaping of historical tradition, and follows the various phases in which that was conceived and set forth. It contains, so to speak, a history of tradition. The third part sums up the critical results of the preceding two, with some further determining considerations, and concludes with a more general survey. The assumptions I make will find an ever-recurring justification in the course of the investigation; the two principal are, that the work of the Jehovist, so far as the nucleus of it is concerned, belongs to the course of the Assyrian period, and that Deuteronomy belongs to its close. Moreover, however strongly I am convinced that the latter is to be dated in accordance with 2Kings xxii., I do not, like Graf, so use this position as to make it the fulcrum for my lever. Deuteronomy is the starting-point, not in the sense that without it it would be impossible to accomplish anything, but only because, when its position has been historically ascertained, we cannot decline to go on, but must demand that the position of the Priestly Code should also be fixed by reference to history. My inquiry proceeds on a broader basis than that of Graf, and comes nearer to that of Vatke, from whom indeed I gratefully acknowledge myself to have learnt best and most. A.
