The authors are preparing a volume for the Yale Anchor Bible Reference Library, Deuteronomy and the Pentateuch, which will examine the following key questions: (1) What is the date and historical context for the composition of Deuteronomy? (2) What is Deuteronomy’s method of composition? (3) What is the relationship between law and narrative in Deuteronomy? (4) What is the intent of Deuteronomy vis-à-vis its Israelite sources? (5) What is the influence of cuneiform legal and treaty traditions upon Deuteronomy and its Israelite forebears? (6) What is Deuteronomy’s status within the compiled Pentateuch (and the larger biblical canon)? In this article, the authors summarize these issues and then examine Deut 13 and its relevance for dealing with each of them.
