In the last two decades, increasing numbers of texts have been suggested as coming from or edited during the Persian period, but these discussions do not always reflect extensively on the assumptions used in making these claims or the implications on a broader scale. Earlier generations of scholars found it sufficient to categorize material in the biblical books simply as "late" or "postexilic" without adequately trying to determine when, by whom, and why the material was incorporated into the text at a fixed point in the Persian period. By grappling with these questions, the essays in this volume evince a greater degree of precision vis-a-vis dating and historical context. The authors introduce the designations early Persian, middle Persian, and late Persian in their textual analysis, and collectively they take significant steps toward developing criteria for locating a biblical text within the Persian period.
