It will be necessary to prefix a few further remarks on the Davidic psalms in general. Can we tell which are David's? The Psalter, as is generally known, is divided into five books or parts, probably from some idea that it corresponded with the Pentateuch. These five books are marked by a doxology at the close of each, except the last. The first portion consists of Psa. i.-xli.; the second of Psa. xlii.-lxxii; the third of Psa. lxxiii.-lxxxix; the fourth of Psa. xc.-cvi.; and the fifth of Psa. cvii.-cl. The psalms attributed to David are unequally distributed through these five books. There are seventy-three in all, and they run thus:--In the first book there are thirty-seven; so that if we regard psalms i. and ii. as a kind of double introduction, a frontispiece and vignette title-page to the whole collection, the first book proper only two which are not regarded as David's. The second book has a much smaller proportion, only eighteen out of thirty-one. The third book has but one, the fourth two; while the fifth has fifteen, eight of which (cxxxviii.-cxlv.) occur almost at the close. The intention is obvious--to throw the Davidic psalms as much as possible together in the first two books. And the inference is not unnatural that these may have formed an earlier collection, to which were afterwards added the remaining three, with a considerable body of alleged psalms of David, which had subsequently come to light, placed side by side at the end, so as to round off the whole. Be that as it may, one thing is clear from the arrangement of the Psalter, namely, that the superscriptions which give the authors' names are at least as old as the collection itself; for they have guided the order of the collection in the grouping not only of Davidic psalms, but also of those attributed to the sons of Korah (xlii.-xlix.) and to Asaph (lxxiii.-lxxxiii.) The question of the reliableness of these superscriptions is hotly debated. The balance of modern opinion is decidedly against their genuineness. As in greater matters, so here "the higher criticism" comes to the consideration of their claims with a prejudice against them, and on very arbitrary grounds determines for itself, quite irrespective of these ancient voices, the date and authorship of the psalms. The extreme form of this tendency is to be found in the masterly work of Ewald, who has devoted all his vast power of criticism (and eked it out with all his equally great power of confident assertion) to the book, and has come to the conclusion that we have but eleven of David's psalms,--which is surely a result that may lead to questionings as to the method which has attained it.
