Psalms
The psalms are the production of various authors. “Only a portion of the Book of Psalms claims David as its author. Other inspired poets in successive generations added now one now another contribution to the sacred collection, and thus in the wisdom of Providence it more completely reflects every phase of human emotion and circumstances than it otherwise could.” But it is specially to David and his contemporaries that we owe this precious book. In the “titles” of the psalms, the genuineness of which there is no sufficient reason to doubt, 73 are ascribed to David. Peter and John (Acts 4:25) ascribe to him also the second psalm, which is one of the 48 that are anonymous. About two-thirds of the whole collection have been ascribed to David.
Psalms 39, 62, and 77 are addressed to Jeduthun, to be sung after his manner or in his choir. Psalms 50 and 73-83 are addressed to Asaph, as the master of his choir, to be sung in the worship of God. The “sons of Korah,” who formed a leading part of the Kohathite singers (2 Chr. 20:19), were intrusted with the arranging and singing of Ps. 42, 44-49, 84, 85, 87, and 88.
In Luke 24:44 the word “psalms” means the Hagiographa, i.e., the holy writings, one of the sections into which the Jews divided the Old Testament.
None of the psalms can be proved to have been of a later date than the time of Ezra and Nehemiah, hence the whole collection extends over a period of about 1,000 years. There are in the New Testament 116 direct quotations from the Psalter.
The Psalter is divided, after the analogy of the Pentateuch, into five books, each closing with a doxology or benediction:
