Book of Psalms Summary: The Hymnal of Heaven and the Heartbeat of the Messiah. The Book of Psalms—known in Hebrew as Tehillim (“Praises”)—is the largest book in the Bible and the most quoted in the New Testament. Far from being a disorganized collection of Hebrew poetry, Psalms is a divinely inspired anthology of worship, theology, and prophecy, often functioning as a prophetic commentary on the life of Jesus Christ.
