Title: Revised Standard Version
Content: 1) The Old Testament (39 Books) ; 2) The Catholic Deuterocanonical Books (12 Books) ; 3) The additional Eastern Orthodox Deuterocanonical Books (three Books; six Books after 1977) ; 4) The New Testament (27 Books) The Common Bible of 1973 ordered the books in a way that pleased both Catholics and Protestants. It was divided into four sections: The non-deuterocanonicals gave the Common Bible a total of 81 books: it included 1 Esdras (also known as 3 Ezra), 2 Esdras (4 Ezra), and the Prayer of Manasseh, books that have appeared in the Vulgate's appendix since Jerome's time "lest they perish entirely", but are not 
Title: Biblical canon
Content:  Martin Luther (1483–1546) moved seven Old Testament books (Tobit, Judith, 1–2 Maccabees, Book of Wisdom, Sirach, and Baruch) into a section he called the "Apocrypha, that are books which are not considered equal to the Holy Scriptures, but are useful and good to read". Luther removed the books of Hebrews, James, Jude and Revelation from the canon partially because some were perceived to go against certain Protestant doctrines such as sola scriptura and sola fide, while defenders of Luther cite previous scholarly precedent and support as the justification for his marginalization of certain books, including 2 Maccabees Luther's smaller canon was not fully accepted in Protestantism, though apocryphal books are 
Title: Old Testament
Content:  In the 16th century, the Protestant reformers sided with Jerome; yet although most Protestant Bibles now have only those books that appear in the Hebrew Bible, the order is that of the Greek Bible. Rome then officially adopted a canon, the Canon of Trent, which is seen as following Augustine's Carthaginian Councils or the Council of Rome, and includes most, but not all, of the Septuagint (3 Ezra and 3 and 4 Maccabees are excluded); the Anglicans after the English Civil War adopted a compromise position, restoring the 39 Articles and keeping the extra books that were excluded by the Westminster Confession of Faith, but only for private study and for reading in churches, while Lutherans kept them for private study, gathered in an appendix as biblical apocrypha.
Title: Deuterocanonical books
Content: The Epistle to the Hebrews ; The Epistle of James ; The Second Epistle of Peter ; The Second Epistle of John ; The Third Epistle of John ; The Epistle of Jude ; The Apocalypse of John (also known as the Book of Revelation) The term deuterocanonical is sometimes used to describe the canonical antilegomena, those books of the New Testament which, like the deuterocanonicals of the Old Testament, were not universally accepted by the early Church. These books may be called the "New Testament deuterocanonicals", which are now included in the 27 books of the New Testament recognized by almost all Christians. The deuterocanonicals of the New Testament are as follows: Luther made an attempt to remove the books of Hebrews, James, Jude and Revelation from the canon (notably, he perceived them to go against the doctrines of sola gratia and sola fide), but this was not generally accepted among his followers. However, these books are ordered last in the German-language Luther Bible to this day.
Title: Heptateuch
Content:  The Heptateuch (seven containers) is a name sometimes given to the first seven books of the Hebrew Bible. The seven books are Genesis, Exodus, Leviticus, Numbers, Deuteronomy, Joshua and Judges. The first four of these are sometimes called the Tetrateuch, the first five are commonly known as the Torah or the Pentateuch, the first six as the Hexateuch. With the addition of the Book of Ruth, these eight books are known as the Octateuch. The "Enneateuch" is the Heptateuch plus the Books of Samuel and the Books of Kings (each pair of books counted as one, and not including the Book of Ruth). Augustine of Hippo produced a piece called Questions on the Heptateuch. Ælfric of Eynsham produced an Old English version of the Heptateuch.
Title: New Testament
Content:  27-book canon of the New Testament has been almost universally recognized within Christianity since at least Late Antiquity. Thus, in almost all Christian traditions today, the New Testament consists of 27 books: The earliest known complete list of the 27 books is found in a letter written by Athanasius, a 4th-century bishop of Alexandria, dated to 367 AD. The 27-book New Testament was first formally canonized during the councils of Hippo (393) and Carthage (397) in North Africa. Pope Innocent I ratified the same canon in 405, but it is probable that a Council in Rome in 382 under Pope Damasus I gave the same list first. These councils also provided the canon of the Old Testament, which included the apocryphal books. 
Title: Bible
Content:  number of books which are part of the Peshitta or the Greek Septuagint but are not found in the Hebrew Bible (i.e., among the protocanonical books) are often referred to as deuterocanonical books by Roman Catholics referring to a later secondary (i.e., deutero) canon, that canon as fixed definitively by the Council of Trent 1545–1563. It includes 46 books for the Old Testament (45 if Jeremiah and Lamentations are counted as one) and 27 for the New. Eighty book Protestant Bibles have fourteen books in between the Old Testament and New Testament in a section called the Apocrypha. Protestant traditions traditionally

The Sages taught that inverted nuns ( ] ) bracket the verses, about how the Ark would move, to teach that the verses are not in their proper place. But Rabbi said that the nuns do not appear there on that account, but because constitute a separate book. It thus follows according to Rabbi that there are seven books of the Torah, and this accords with the interpretation that Rabbi Samuel bar Nahmani made in the name of Rabbi Jonathan of, when it says, "She [Wisdom] has hewn out her

Content:  sacred scriptures of most Christian groups are the Old Testament and the New Testament. Latin Bibles originally contained 73 books; however, 7 books, collectively called the Apocrypha or Deuterocanon depending on one's opinion of them, were removed by Martin Luther due to a lack of original Hebrew sources, and now vary on their inclusion between denominations. Greek Bibles contain additional materials. The New Testament comprises four accounts of the life and teachings of Jesus (the Four Gospels), as well as several other writings (the epistles) and the Book of Revelation. They are usually considered to be divinely inspired, and together comprise the

Yohanan: “She hath hewn out her seven pillars” (Proverbs 9:1) &ndash; these are the seven books of the Pentateuch; according to whom? According to Rabbi Judah Hanasi." - Shabbat 115b&ndash;116a Bar Kappara is known to have considered the Torah as composed of seven volumes in the Gemara "The seven pillars with which Wisdom built her house (Prov. 9:1) are the seven Books of Moses".
