I’m missing the book name you want — the quotes are empty. Which Bible book do you mean?

If helpful, here are some common possibilities I can expand on from an evangelical perspective (pick one or more):
– Genesis — traditionally Moses
– Exodus, Leviticus, Numbers, Deuteronomy — traditionally Moses
– Psalms — largely David (with other authors)
– Isaiah — Isaiah (with some evangelicals holding to one author, some to multiple)
– Jeremiah, Ezekiel, Daniel — the prophets named in their books
– Matthew, Mark, Luke, John — the four Gospel authors (Matthew the tax collector, Mark the interpreter of Peter, Luke the physician/companion of Paul, John the apostle)
– Acts — Luke (the physician and companion of Paul)
– Romans through Philemon — Paul (letters to churches and individuals)
– Hebrews — debated (historic evangelical views vary; some attribute to Paul, Luke, or Barnabas, but many evangelical scholars treat the author as anonymous)
– James — James (traditionally the brother of Jesus)
– 1–2 Peter — Peter (though some evangelicals discuss stylistic issues)
– Jude — Jude (brother of Jesus)
– Revelation — John (most evangelicals identify John the Apostle or John of Patmos)

Tell me which book (or books) you want info about, and I’ll share the evangelical view of the most-likely author, the reasons for that view, key internal/external evidence, and pastoral/theological significance.
