Tanakh, Tanakh

The three-part division reflected in the acronym "Tanakh" is well attested to in documents from the Second Temple period and in Rabbinic literature. http://www.ucalgary.ca/~elsegal/TalmudMap/MG.html#MG Mikra'ot Gedolot During that period, however, "Tanakh" was not used as a word or term. Instead, the proper title was Mikra , because the biblical texts were read publicly. "Mikra" is thus analogous to the Latin term Scriptus , meaning "that which is written" (as in "Scripture" or "The Holy Scriptures").

According to Jewish tradition, the Tanakh consists of twenty-four books.
