Many people are told that we can’t be sure who wrote the Bible. But the Bible is often clear about who penned its contents. Some parts begin with such phrases as “the words of Nehemiah,” “the vision of Isaiah,” and “the word of Jehovah that occurred to Joel.”—Nehemiah 1:1; Isaiah 1:1; Joel 1:1.
Most Bible writers acknowledged that they wrote in the name of Jehovah, the one true God, and that they were guided by him. Prophets who wrote the Hebrew Scriptures proclaimed more than 300 times: “This is what Jehovah has said.” (Amos 1:3; Micah 2:3; Nahum 1:12) Other writers received God’s message through angels.—Zechariah 1:7, 9.
The Bible was written by some 40 men over the course of 1,600 years. Some men were used to write more than one book of the Bible. In fact, the Bible is a miniature library of 66 books. It consists of the 39 books of the Hebrew Scriptures, called by many the Old Testament, and the 27 books of the Christian Greek Scriptures, often called the New Testament.
