The Bible (from Koine Greek τὰ βιβλία, tà biblía, "the books") is a canonical collection of texts considered sacred in Judaism or Christianity. Different religious groups include different books within their canons, in different orders, and sometimes divide or combine books, or incorporate additional material into canonical books. Christian Bibles range from the sixty-six books of the Protestant canon to the eighty-one books of the Ethiopian Orthodox Church canon.

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"). 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 than the Hebrew Bible. The Catholic Church and Eastern Christian churches also hold certain deuterocanonical books and passages to be part of the Old Testament canon. The second part is the New Testament, containing twenty-seven books; the four Canonical gospels, Acts of the Apostles, twenty-one Epistles or letters and the Book of Revelation.
