Except Wisdom and 2Machabees, which were composed in Greek, all of the Old Testament books were written originally in Hebrew, in the old Phenician characters (later exchanged for the "square" script), but without vowels, separation of words, or division into chapters and verses. These elements were introduced later. The present Hebrew Bible contains only the protocanonical books; the Deuterocanonical books, except a part of Ecclesiasticus, are no longer extant in Hebrew.
