The Book of Isaiah: Its Composition History

This chapter discusses the complex literary growth (Redaktionsgeschichte) that lies behind Isa 1–66, with special focus on history of research. The most important contribution can be attributed to Bernhard Duhm, who proposed the three-part division of Isaiah into Proto-Isaiah, Deutero-Isaiah, and Trito-Isaiah. He had several forerunners in the eighteenth century. The great success of the idea of a tripartite authorship stems from Duhm’s conception of the prophet—the prophet was a rhetorical and religious genius. The second part of the chapter deals with the “Rediscovery of the Essential Unity of the Book.” One can speak of a paradigm shift, when the person of the prophet has been replaced by an interest in the book as a literary. There are two basic models for understanding the origin of the book. In the first model, Isa 1–39 and 40–55 are traced back to two, initially independently transmitted, literary works. According to the second model, Isa 40–55 is a literary continuation of Isa 1–39, making it necessary to dismiss the notion of an autonomous Deutero-Isaiah. Two conclusions can be drawn from the history of research: (a) the person of the prophet can no longer serve as an appropriate point of departure for analysis, and (b) redaction-critical analysis of Isa 1–39 must always proceed with attention to the whole book of Isaiah.
