Biblical books are the texts that make up the Bible, a sacred scripture in Christianity and Judaism. The Bible is divided into two main sections: the Old Testament, which contains texts sacred to both religions, and the New Testament, which focuses on the life and teachings of Jesus Christ and the early Christian community. There are a total of 66 books in the Protestant Bible, while the Catholic Bible includes additional texts known as the Deuterocanonical books. Each book varies in genre, including history, poetry, prophecy, and letters, contributing to the rich tapestry of religious literature.
