This book review examines the first two volumes of the JPS Torah Commentary series: Genesis by Nahum M. Sarna and Leviticus by Baruch A. Levine. The review employs a comparative analysis methodology, evaluating each commentary's scholarly approach, use of traditional Jewish sources, and treatment of critical biblical scholarship. The main findings indicate that both volumes represent high-caliber scholarship combining modern academic insights with classical Jewish exegesis, though they differ significantly in their approaches to higher criticism and textual analysis. Sarna adopts a literary-unified approach, treating Genesis as a coherent document while largely avoiding documentary hypothesis discussions, whereas Levine openly engages with critical scholarship and developmental theories regarding Leviticus' composition. Both authors demonstrate mastery in their respective strengths: Sarna excels in cross-cultural analysis and literary techniques, while Levine focuses on internal textual relationships and priestly traditions. The review concludes that these commentaries successfully fulfill Orlinsky's prediction of launching "an age of commentary," providing scholarly works that bridge traditional Jewish interpretation with contemporary biblical studies. However, the analysis notes limitations in their engagement with modern Hebrew scholarship and recent traditional commentators, suggesting areas for future enhancement in the series.
