David's Name on a Book Many Hands Wrote

Psalms carries David's name more prominently than any other single figure, reflecting both the many psalms directly attributed to him and his broader role in tradition as Israel's musician-king, the one who, per the book of Samuel, played the lyre to soothe Saul and organized Temple musical service later tradition credits him with founding. Yet the collection's own internal evidence undercuts any simple single-author reading: barely half its psalms carry a Davidic superscription, other named contributors span centuries, and about a third of the book is anonymous, pointing critical scholars toward a compiled anthology assembled gradually across the First and Second Temple periods rather than the output of one royal poet. The book's liturgical role has if anything grown rather than diminished across the centuries since: it structures the entire cycle of monastic daily prayer in both Eastern and Western Christian tradition, where the whole Psalter is typically recited on a rotating schedule of weeks, and remains central to synagogue liturgy, particularly the Hallel psalms sung on festivals.

The Qumran discoveries added a genuine wrinkle to the book's history, since at least one major scroll preserves a substantially different psalm order and includes compositions absent from the later standardized collection, evidence that the boundary and arrangement of the Psalter itself was still being settled as late as the Second Temple period.
