The Book of Psalms is commonly known as the Psalms or the Psalter
and is divided into five sections each closing with a doxology. The
title is derived from the Greek translation ψαλμοί (psalmoi)
meaning "instrumental music" and by extension "the words
accompanying the music". Most if not all are thought be composed by
King David. The Psalms have always been an integral part of the
prayers of the Christian church and especially among monks who
would generally chant all psalms in a week-long cycle. There have
been many commentaries on the Psalms but none perhaps more famous
and widely used than St. Augustine's.
