The Book of I. Eisenberg tells about how the Torah was passed down from generation to generation from the moment it was received by the Jewish people on Mount Sinai to the present day. The author provides information about the structure of the Written Torah, as well as the Oral Torah, starting with the Mishnah and the Talmud, the works of prominent medieval commentators: Reef, Rambam, Rosh, p. Yaakov ben Asher, p. Yosefa Karo, and ending with the works of the so-called "late Posky"; R. Avragama * Danzig, R. Shlomo Ganzfrida, Hafetz-Hayim, etc. The translator and scientific editor have significantly reworked the book, trying to make it as accessible as possible to those who, for the first time, may be familiar with Jewish cultural heritage.
