thoughtful, enlightened judgment of thousands of devoted Christians. Thus through definite historical forces and the minds and wills of men, the Eternal Father gradually perfected the record of his supreme revelation, to humanity. VI THE GROWTH OF THE OLD TESTAMENT PROPHETIC HISTORIES [Sidenote: _Analogies between the influences that produced the two Testaments_] Very similar influences were at work in producing and shaping both the Old and the New Testaments; only in the history of the older Scriptures still other forces can be distinguished. Moreover, the Old Testament contains a much greater variety of literature. It is also significant that, while some of the New Testament books began to be canonized less than a century after they were written, there is clear evidence that many of the Old Testament writings were in existence several centuries before they were gathered together into a canon and thus crystallized into their final form. The inevitable result is that they bear the marks of much more elaborate editorial revision than those of the New. It is, however, not the aim of the present work to trace this complex process of revision in detail, nor to give the cumulative evidence and the many data and reasons that lead to each conclusion. These can be studied in any modern Old Testament introduction or in the volumes of the present writer's _Student's Old Testament_. [Sidenote: _The present classification of the Old Testament books_] In their present form, the books of the Old Testament, like those of the New, fall into three classes. The first includes the historical books. In the Old, corresponding to the four Gospels and Acts of the New, are found the books from Genesis through Esther. Next in order, in the Old, stand the poetical books, from Job through the Song of Songs, with which the New Testament has no analogy except the liturgical hymns connected with the nativity, preserved in the opening chapters of Matthew and Luke. The third group in the Old Testament includes the prophecies from Isaiah through Malachi.
