The Bible is a canonical collection of texts sacred in Judaism and Christianity. There is no single "Bible" and many Bibles with varying contents exist. The term Bible is shared between Judaism and Christianity, although the contents of each of their collections of canonical texts is not the same. Different religious groups include different books within their Biblical canons, in different orders, and sometimes divide or combine books, or incorporate additional material into canonical books.
The Hebrew Bible, or Tanakh, contains twenty-four books divided into three parts: the five books of the Torah ("teaching" or "law"), the Nevi'im ("prophets"), and the Ketuvim ("writings"). Christian Bibles range from the sixty-six books to eighty-one books. The first part of Christian Bibles is the Old Testament, which contains, at minimum, the twenty-four books of the Hebrew Bible divided into thirty-nine books and ordered differently from the Hebrew Bible. The second part is the New Testament, containing twenty-seven books.
