Contents Lecture 1: The Nucleus of the Book of Isaiah Lecture 2: Enlargement of the Original Book of Isaiah by the Addition of Prophecies composed in the Babylonian and Persian Periods Lecture 3: Modification of the Enlarged Book of Isaiah during the Maccabean Period, and Addition to It of Prophecies Recently Composed This volume contains three lectures from the second annual Schweich Lectures of 1909. Written clearly and with the English reader in mind, Kennett's work investigates the redactional history of the book of Isaiah. Among his conclusions is the assignment of over half of the book to the Maccabean era. These lectures serve as a good review of Isaiah scholarship at the turn of the twentieth century.
