The conclusion to Paul Tarazi's triology, this text provides background information on the language, history, and culture of those who first wrote the Psalms. It covers understandings of the words, "king", "God", "Lord", and "righteousness", and seeks to explain how and why the Psalms were used in prayer and what one can learn about prayer itself. The volume's discussion of "Wisdom" literature examines the concept of "scripture", leading to an in-depth explanation of how the Old and New Testaments make up a single, unified Christian Scripture in which both testaments have essential roles.
