Christoph Berner provides a comprehensive redaction-critical analysis of the literary development of the Exodus narrative (Ex 1-15) and the closely related chapter on Jethro (Ex 18). He shows that the present form of the text does not result from the compilation of sources, nor was it the work of one or a few large-scale redactions. Rather, it is the product of a continuous process of literary expansions through which the foundation myth of the Exodus constantly gained narrative complexity and theological depth.
