The world of sages opened at a time when the gates of prophecy in Israel were closed. Many challenges faced them from home and abroad: the establishment of the Hasmonean state and its disintegration and social processes that led to the destruction of the house. The sages knew that they had to build a solid spiritual infrastructure in order to preserve the Jewish tradition for generations. The historical burden placed on their shoulders is reflected in the development and foundation of the world of Halacha, as well as an extensive moral work. Their moral voice, articulated in the Tract of the Fathers, echoed like the lost voice of the prophets, and it sounds clear to this day. This volume of the book "Sages" is the first in the series, and it follows the work of the sages, beginning with the work of the members of the Great Knesset until the destruction of the Temple. The book listens to the voices emanating from the midrash houses during the Second Temple period and reveals the spiritual and religious world that stands behind them. The book "Sages" adheres as much as possible to both the historical events and the tractate of Avot, and equips the reader with the tools for a thorough understanding of the Oral Torah and paints it in an instructive topical light.
