The book of Psalms has a broad range of content and style. New Testament writers quoted from Psalms more than any other Old Testament book. Numerous people wrote Psalms, such as David, Moses, and Solomon. The Psalms have been a source of encouragement and strength for God's people, and they still speak to us today. God's people have sung many of the Psalms during times of worship, according to the Apostle Paul (Ephesians 5:19).
