Psalm Book
A collection of Psalms, the Psalter, or the Psalm Book, is one of the poetic books of the Old Testament. The Psalm Book contains 151 Psalms, of which 150 are canonical, and the last one is deuterocanonical. In the Bible, the Psalm Book bears the name of King David, "The Psalm Book of David". However, the majority of Psalms are anonymous, and the titles of some Psalms mention other authors too, as Moses, Solomon, Asaph, Heman, Ethan, Korahites. The Psalm Book took its present form by the hand of its editor, Priest Ezra (5th century B.C.)
