should expect to find that Book I. contained the earliest Psalms and Books IV. and V. the latest; this is roughly correct, if we allow for the possibility of minor insertions being made for various purposes in the last edition. In Book V. there is a group of Psalms (civ.-cvi., cxi.-cxiii., cxv.-cxvii., cxxxv., cxlvi.-cl.), which are distinguished by either commencing or ending with "Hallelujah," and are known as the "Hallels." From their contents, it may be observed that they are suitable for use at the Great Festivals, and it is known that they were, and are still so used by the Jews. They imply a highly organised musical service (Ps. cl.), they require a time when the festivals were regularly observed and when the worship of the Temple could be carried on without fear. Such conditions are to be found together only after the Exile, and then only during the period of Greek rule; and to this late period the composition of these Psalms is to be referred. An even later date is demanded for some Psalms that are said to reflect the rebellion against the Hellenizing movement enforced by Antiochus Epiphanes, in which the Maccabees played such a heroic part. This date is confirmed by the references to: the "assembly of the saints" (Ps. cxlix. 1, Heb. _hasidim_, the purist party formed in that time); the cruel persecution for religious opinions (Ps. xliv. 17-22; lxxix. 2; lxxxiii. 3, 4); the defiling of the Temple, the burning of the synagogues, and the silence of the Prophetic voice (Ps. lxxiv. 7-9; lxxix. 1). Other Maccabæan Psalms are said to be: cx., where there is a reference to some priest who is not in the legitimate succession, which entirely describes the Priest-Kings of the Maccabæan dynasty (other scholars would put this Psalm very early; on the other hand there are alleged traces of an acrostic that would spell Simon, the first of the Maccabæan Priest-Kings); cxv. cxviii., which celebrate successful wars in which the leaders have been the house of Aaron, to which house the Maccabees of course belonged. This is the latest date that is demanded for any of the Psalms, and in the present condition of criticism we can only say that between this and some earlier period the book is to be placed. It must now be our task to discover the earliest date that any of the Psalms demand. We have seen that Book I. seems to be the earliest collection, and tradition assumes that this was the work of David and was the Psalm Book used in the First Temple. To discuss this point it is necessary to enquire into the reliability of the titles that ascribe the Psalms to definite authors. These titles give: one each to Moses, Ethan, and Heman; two to Solomon; eleven to the Sons of Korah; twelve to Asaph; and seventy-three to David (it is doubtful whether Jeduthun is a person; if so he is probably the same as Ethan: Ps. xxxix., lxii., lxxvii., titles; cp. 1 Chron. vi. 44 with 1 Chron. ix. 16). Now it should be noticed that none of the authors are later
