Heptateuch Heptateuch The Heptateuch (seven containers) is a name sometimes given to the first seven books of the Hebrew Bible. The seven books are Genesis, Exodus, Leviticus, Numbers, Deuteronomy, Joshua and Judges. The first four of these are sometimes called the Tetrateuch, the first five are commonly known as the Torah or the Pentateuch, the first six as the Hexateuch. With the addition of the Book of Ruth, it becomes the Octateuch. The "Enneateuch" is the Heptateuch plus the Books of Samuel and the Books of Kings (each pair of books counted as one, and not including the Book of Ruth).
Development of the Old Testament canon "Apocrypha" ("hidden"). To counter Luther's "heresy", the fourth session of the Catholic Council of Trent in 1546 confirmed that the deuterocanonical books were equally authoritative as the protocanonical in the Canon of Trent in the year Luther died. Following Jerome's "Veritas Hebraica" (truth of the Hebrew) principle, the Protestant Old Testament consists of the same books as the Hebrew Bible, but the order and division of the books are different. Protestants number the Old Testament books at 39, while the Hebrew Bible numbers the same books as 24. The Hebrew Bible counts Samuel, Kings, and Chronicles as one book each,
