The genesis of the book of Proverbs is exceedingly helpful in tracing the closely analogous growth of the Psalter. The prevailing form of the superscriptions and the predominant use of the name _Jehovah_ or _Elohim_ also aid in this difficult task. Psalms i. and ii. are introductory to the entire book. Psalms iii-xli. all bear the Davidic superscription and use the designation _Jehovah_ two hundred and seventy-two times, but _Elohim_ only fifteen. The form and contents of these psalms, as well as their position, suggest that they are the oldest collection in the book. In the Greek version all the psalms of the collection found in li-lxxii., excepting Psalm lxvi., which is anonymous, and lxxii., which is attributed to Solomon, have also the Davidic superscription. Although certain subsequent psalms are ascribed to David, as, for example, lxxxvi., ci., and ciii., the close of the collection, is the significant epilogue (lxxii. 20), _the prayers of David the son of Jesse are ended._ [Sidenote: _Meaning and value of the superscriptions_ ] Before the approximate date of these collections can be determined the significance of the Davidic title needs interpretation. In the Hebrew version, this title is borne by seventy-three psalms. Two are ascribed to Solomon (lxxii. and cxxvii.), one to Moses (xc.), and twenty-four to the members of the post-exilic guilds of temple singers. The superscriptions of the Greek and Syrian versions contain many variations from those in the Hebrew. This is probably due to the fact that superscriptions are usually added by later scribes in whose minds the question of authorship first became prominent. In earlier Hebrew the phrase commonly translated _Psalm of David_ would more naturally mean a _psalm for David_ or _dedicated_ or _attributed to David._ The latter appears to have been its original significance. Like the title, _Proverbs of Solomon,_ it was used to distinguish an ancient poem, which, being a psalm, was naturally ascribed to David, and to him later Judaism, in common with the New Testament writers, attributed all psalm literature. A detailed study of the superscriptions soon demonstrates that the majority of them represent only the conjectures of scribes who were guided by current traditions or suggestions embodied in the psalms themselves. In this manner, to Solomon, the builder of the temple, is ascribed Psalm cxxvii., because it refers to the building of the house in its opening verse. The Greek version even attributes to David Psalm xcvi., which, it states, was written _when the temple was being built after the captivity._ [Sidenote: _David's relation to the psalter_]
