But if our book, as we have it, is not by Moses, but is an account by another person of what Moses did and said on a certain occasion, that fact has a very important bearing upon the speeches reported as Mosaic. For the style of the whole book up to the end of the twenty-eighth chapter is, for all practical purposes, one. The parts where the author speaks, and the parts where Moses speaks, are all alike in style, and that style is in all respects different from the style of the speeches attributed to Moses in other parts of the Pentateuch. Consequently we cannot accept the speeches and laws as being in the very words of Moses. They may contain the exact ideas of Moses, but these have manifestly passed through the mind and clothed themselves in the vocabulary of the author of Deuteronomy. Even Delitzsch is quite decisive on this point.[5] In the tenth of his _Pentateuch Kritische Studien_, after distinguishing the Deuteronomist from Moses, he continues thus: "The addresses are freely reproduced, and he who reproduces them is the same who also contributed the historical framework and the historical details between the addresses. The same colouring, though in a less degree, may also be remarked in the repetition of the law in chapters xii.-xxvi. to which the book owes its name. All the component parts of Deuteronomy, not excepting the legal prescriptions, are woven through and through with the favourite phrases of the Deuteronomist." [5] Cf. _Pentateuch Kritische Studien_ in Luthardt's _Zeitschrift_, 1880. Under these circumstances, the question immediately suggests itself to what degree this representation of Moses' legislation can be regarded as purely and unmixedly Mosaic. Was this legislation given in the main or entirely by Moses, and, if it was so given, may there not be mingled with what he gave inferences drawn by the author in whose style the book is written, and adaptations demanded by the exigencies of his later times? A full discussion of this point would, of course, be out of the question here, and it would, moreover, be superfluous. In Dr. Driver's article on "Deuteronomy" in Smith's _Dictionary of the Bible_, and in his _Introduction to Hebrew Literature_, detailed discussions will be found. All that is necessary here is that one or two large and salient aspects of the question should be looked at.
