The concern for purity was the cornerstone of the religious culture of ancient Judaism, shaping the worldview of Jewish people during the Second Temple period as well as their daily practices and social relations. In his book, Purity and Identity in Ancient Judaism: From the Temple to the Mishnah (Indiana UP, 2023), Yair Furstenberg examines how different groups offered competing visions and methods for living a life of purity, which embodied a promise for personal and cosmic salvation and at the same time determined the degree of sectarian separation.  Yair Furstenberg is Associate Professor and Chair of the department of Talmud at Hebrew University, and has also published: Jewish Martyrdom in Antiquity: From the Books of Maccabees to the Babylonian Talmud. Michael Morales is Professor of Biblical Studies at Greenville Presbyterian Theological Seminary, and the author of The Tabernacle Pre-Figured: Cosmic Mountain Ideology in Genesis and Exodus(Peeters, 2012), Who Shall Ascend the Mountain of the Lord?: A Biblical Theology of Leviticus (IVP Academic, 2015), and Exodus Old and New: A Biblical Theology of Redemption (IVP Academic, 2020).
