The Hebrew Bible includes some small portions in Aramaic (mostly in the books of Daniel and Ezra), which are nonetheless written and printed in the Hebrew alphabet and script, which is the same as Aramaic square-script . Some Qumran Hebrew biblical manuscripts are written using the Paleo-Hebrew alphabet of the classical era of Solomon's Temple.
This is another reason non-confessional terms like Hebrew Bible suit themselves to academic, and other, discourse.
On the other hand, it is widely used in academic writing and interfaith discussion. In short, the term 'Hebrew Bible' is mostly to be found employed in relatively neutral contexts that are meant to include dialogue amongst all religious traditions, but not widely found in the inner discourse of the religions which use its text.
Thus the term "Hebrew Bible" corresponds most fully to the Old Testament in use by Protestant denominations (adhering to Jerome's Hebraica veritas doctrine), and less fully to canons that are based closely on the Septuagint (adhering to Augustine's 393 Synod of Hippo and 397-419 Councils of Carthage).
