Hexateuchal Redaction in Joshua

The present paper looks for a Hexateuchal redaction in Joshua, not for an original Hexateuch, i. e., a literary work that from the outset covered the exodus and conquest. This question is posed by Joshua 24. For in this chapter, we clearly observe the endeavor to delimit a fairly fully developed proto-Pentateuch and an equally elaborate book of Joshua as a literary unit within the larger narrative continuum, thus establishing the Hexateuch as a discrete work ex post facto. The latter observation is well documented and gains growing acceptance in critical scholarship. All the more apparent is the lack of studies devoted to Hexateuchal redaction of the Joshua story outside of Joshua 24. Given the determined attempt in that chapter to establish the Hexateuch as a redactional unit, and taking into account the deliberate reworking of preceding parts of the Pentateuch for this end, should one not expect that same redactor – or else some successor – to have reworked other parts of Joshua as well?
