In Judaism, the study is a religious duty, because the pious Jew's life is governed by the requirements of the Torah. Therefore, Judaism is a religion of the book, of the study of the Scriptures. This explains the organization of a Hebrew educational system at all levels, in all times and in all the places inhabited by Jews, as one of the major concerns of any community, illiteracy being almost unknown. The same happened in the Jewish community in Arad, one of the representative communities of Transylvania where, in time, there were various Jewish educational institutions, both religious and secular: elementary school, high school, Torah Talmud or yeshiva. A bibliography is included.
