Book excerpt: These essays are written in honour of John D.W. Watts, formerly Professor of Old Testament at Southern Baptist Seminary, Louisville, Kentucky and Old Testament editor of the Word Biblical Commentary, well known for his contributions, especially to scholarship on the prophetic books. Accordingly, the essays here address the literary, redactional and canonical questions posed by the Hebrew Bible's prophetic literature. The prophetic books have defied easy classification according to genre or facile explanation of their historical development. With a special focus on the books of Isaiah and of the Twelve Prophets, the nature and formation of prophecy as literature is probed from a variety of methodological standpoints, including textual criticism, synchronic literary analysis, tradition history and redaction criticism.
