The book Mah Nishtannah: The Passover Night in the Sages' Discourse seeks to provide novel answers, based upon up-to-date methods of scholarly Talmud analysis, to ancient questions raised by the Seder Night, a night at the focus of Jewish culture from time immemorial. The book analyzes the focal points of this night – the Passover meal and its commandments on one hand, and the foundation of the Haggadah and the development of its design and history of its structure on the other.

This book examines the Rabbinic perception of the biblical commandment of pilgrimage-related joy - “You shall rejoice on your festival” - from the Second Temple through the tannaitic-amoraic period. Close analysis of the sources discloses an edifice of early tannaitic halakhah concerning the festivals and pinpoints the development of its underlying conceptual-exegetical approach from early teachings to its present form.
