In the light of the phenomena we have already observed, we may confidently infer that there was once a collection of religious lyrics bearing some such title as "Hymns of David." So long as this book had a separate existence, the name would naturally not be repeated at the head of the individual poems in it; such repetition became necessary, however, when psalms from this book were taken up into a larger hymn book containing not only psalms from the Korahite and Asaphite collections but many anonymous hymns; just as the name of Charles Wesley would be attached to one of his hymns only when it was taken out of his own volume and included in a composite hymn book. By good fortune we have the colophon of this Davidic Psalter in Ps. lxxii. 20, in the words of a scribe: "The Prayers (an older name for Psalms) of David son of Jesse are finished," that is, the roll containing them is copied to the end--a very common Oriental form of colophon. Curiously enough, the hymn to which this note is annexed is said in its title to be by Solomon, to whom Ps. 127 (one of the Songs of Degrees) is similarly attributed. In both cases the ground of the ascription is plain: the editor thought that Ps. cxxvii. 1 referred to the building of the temple, while the prayer for wisdom with which Ps. 72 begins suggested to him Solomon's dream, 1 Kings 3. From this Davidic hymn book came what is now the first book of the Psalter entire, except Ps. 1 and probably 2; further the groups in Book II. (51-65, 68-70, with 72), which probably stood immediately after Ps. 41. For it will be noted that the second (elohistic) part of the present Psalter (Pss. 42-89) is made up of Korahite, Asaphite, and Davidic psalms, and that in their present position the Davidic psalms, say Pss. 51-72, are thrust into the otherwise solid group of Asaphite hymns Pss. 50 ... 73-83. Further, the transposition of the Davidic psalms to the beginning of the book would bring the hymns of the guilds together. The elohistic recension does not extend consistently beyond Ps. 83; and Pss. 84-89 (Korahite) may therefore be regarded as a supplementary extract from the guild book.
