The Old Testament consists of 46 books in the Catholic Bible, while Protestant Bibles include 39 books. These texts were written over centuries and hold deep religious, historical, and moral significance. The books are divided into four sections: the Books of Moses, the Books of History, the Books of Wisdom, and the Books of the Prophets.
Different Christian traditions recognize different canonical books. The Catholic Old Testament includes the Deuterocanonical books, which are absent from the Protestant Old Testament. These books are sometimes referred to as the Apocrypha by those who do not consider them scripture.
