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.
Bible Many different authors contributed to the Bible. What is regarded as canonical text differs depending on traditions and groups; a number of Bible canons have evolved, with overlapping and diverging contents.[2] The Christian Old Testament overlaps with the Hebrew Bible and the Greek Septuagint; the Hebrew Bible is known in Judaism as the Tanakh. The New Testament is a collection of writings by early Christians, believed to be mostly Jewish disciples of Christ, written in first-century Koine Greek. These early Christian Greek writings consist of narratives, letters, and apocalyptic writings. Among Christian denominations there is some disagreement about the contents of the canon, primarily the Apocrypha, a list of works that are regarded with varying levels of respect.
