Tanakh is an acronym of the first Hebrew letter of each of the Masoretic Text's three traditional subdivisions: Torah (Teaching, also known as the Five Books of Moses), Nevi'im (Prophets) and Ketuvim (Writings)—hence TaNaKh.he three-part division reflected in the acronym Tanakh is well attested in literature of the Rabbinic period. During that period, however, Tanakh was not used. Instead, the proper title was Mikra (or Miqra, מקרא, meaning reading or that which is read) because the biblical texts were read publicly.
