Most modern versions of the Bible contain 66 books, 39 in the Old Testament and 27 in the New Testament. Originally, the number of books in the Bible was 49. First century Jews believed there were 22 holy books that comprised the complete number of their divine scriptures. But in almost all modern versions it is common to numerate the Old Testament as 39 books. The 39 Old Testament books actually comes from 22 books originally by combining several books into one (e.g., they combine the twelve Minor Prophets into one book). The New Testament has remained at 27 books since early times. A complete list appears below
