A dating of the Yahwistic source in the Pentateuch as later than Deuteronomy also has serious implications for the history of law in the Pentateuch, because it means dating the so-called Covenant Code of Exodus 21-23 later than Deuteronomy instead of earlier and suggests a major revision in the development of Hebrew law. Van Seters attempts just such a reevaluation of legal history among the biblical codes in "A Law Book for the Diaspora: Revision in the Study of the Covenant Code"(2003).
