Hexateuch, the name given to the first six books of the Old Testament (the Pentateuch and Joshua), to mark the fact that these form one literary whole, describing the early traditional history of the Israelites from the creation of the world to the conquest of Palestine and the origin of their national institutions. These books are the result of an intricate literary process, on which see Bible (Old Testament: Canon), and the articles on the separate books (Genesis, Exodus, Leviticus, Numbers, Deuteronomy and Joshua).
