Afterlives of the Two Models in Jewish Literature

Abstract Chapter 7 explores the interplay between qualitative and quantitative models of pollution in rabbinic literatures, which were heir to both the Biblical qualitative model and the late Second Temple quantitative model. The chapter demonstrates how the tension between these two models shaped the development of halakhic thought. It does so by contrasting the concept of hierarchic pollution in 4Q274 with rabbinic approaches, which, while recognizing a hierarchy and often paying lip service to the quantitative model, often prioritize specific qualities of individual pollutants over a general ranking system. Specifically, the chapter examines the complex issue of “compoundment,” whereby a single object is exposed to multiple pollutions. By analyzing certain talmudic thought-experiments, the chapter reveals the limitations of a purely quantitative approach and highlights the enduring influence of qualitative considerations in Jewish ritual law.
