3 groups of books in the old testament
Old Testament Christians traditionally divide the Old Testament into four sections: (1) the first five books or Pentateuch (Torah); (2) the history books telling the history of the Israelites, from their conquest of Canaan to their defeat and exile in Babylon; (3) the poetic and "Wisdom books" dealing, in various forms, with questions of good and evil in the world; and (4) the books of the biblical prophets, warning of the consequences of turning away from God.
Old Testament The Old Testament (abbreviated OT) is the first part of Christian Bibles, based primarily upon the Hebrew Bible (or Tanakh), a collection of ancient religious writings by the Israelites[1][need quotation to verify] believed by most Christians and religious Jews to be the sacred Word of God.[2] The second part of the Christian Bible is the New Testament.
