The Book of Psalms commonly referred to simply as Psalms the Psalter or "the Psalms" is the first book of the Ketuvim ("Writings") the third section of the Hebrew Bible and thus a book of the Christian Old Testament. The title is derived from the Greek translation ψαλμοί psalmoi meaning "instrumental music" and by extension "the words accompanying the music". The book is an anthology of individual psalms with 150 in the Jewish and Western Christian tradition and more in the Eastern Christian churches. Many are linked to the name of David. In fact of the 150 Psalms David is named as the author of only 75. David is specifically noted as the author of 73 psalms in the titles of the psalms but his authorship is not accepted by some highly critical modern scholars.
