Original sentence: Additionally the Catholic bible has 3 additional chapters of Daniel and 6 additional chapters of Esther.Other Christian denominations and the Catholic Church have even more books in their Old Testament, taken from the Jewish Septuagint because they retained the books later removed by the protestant reformers.The Catholic Old Testment has 7 books that are entirely absent from the Protestant Old Testament.These are Tobias, Judith, Wisdom, Ecclesiasticus/Sirach, Baruch, I Maccabees, and II Maccabees).These books are called deuterocanonical books.This leaves the Catholic bible with a total of 73 books, and the Protestant bible with 66 books
