Job was the first biblical book to be written. It is asserted that Moses wrote it in 1450 B.C. The last book to be written was Revelation, supposedly written in A.D. 96. Many believe the apostle John wrote this took while he was exiled on the island of Patmos by the Roman emporer Domitian. At this time, John was the sole surviving apostle. An alternative viewpoint from a minority group of scholars is that the dates for the Biblical books cannot be determined.
