Unlike other books, the Holy Bible was not produced as one writing, by one author, at one time. Instead, the Holy Bible is a collection of many works written by forty or more authors and contributors, generally independently of each other over a period of what is commonly believed to be about 1,000 years for the Old Testament and approximately 100 years for the New Testament. There was an approximately 400 year gap between the writings of the two testaments. Thus, the total time span of the writings from beginning to end was approximately 1,500 years. Those works were eventually brought together into a unit to form what we now call the Holy Bible.
