Original: The Hebrew Bible (also Hebrew Scriptures, Latin Biblia Hebraica) is a term used by biblical scholars to refer to the Jewish Bible (Tanakh). It takes its name from the fact that the Jewish Bible is composed mostly in Biblical Hebrew, with a few passages in Biblical Aramaic (about half of the Book of Daniel, some parts of the Book of Ezra and a few other passages).
Simplified: The term Hebrew Bible means books of the Bible that were originally written in Hebrew, and of which people agree that they belong to the Biblical canon.
