Psalm

Many of the psalms contain attributions to the name of King David and other Biblical figures, including Asaph, the sons of Korah, Moses, and Solomon. Davidic authorship of the Psalms is not accepted as a historical fact by modern scholars, who view it as a way to link biblical writings to well-known figures; while the dating of the Psalms is "notoriously difficult", some are considered preexilic and others postexilic. The Dead Sea Scrolls suggest that the ordering and content of the later psalms (Psalms 90–150) was not fixed as of the mid-1st century CE. Septuagint scholars, including Eugene Ulrich, have argued that the Hebrew Psalter was not closed until the 1st century CE.
