Khaboris Codex: The Khaburis Codex (alternate spelling Khaboris, Khabouris) is a medieval era Aramaic manuscript of the New Testament.  The Khaburis Codex is the complete Peshitta New Testament containing 22 books, in comparison to the Western New Testament canon which contains 27 books.  The missing books are known as the "Western Five," namely, 2 Peter, 2 John, 3 John, Jude and Revelation.

Concordant Version: The Concordant Version is an English translation of the Bible compiled by the Concordant Publishing Concern (CPC), which was founded by Adolph Ernst Knoch in 1909.  The principal works of the CPC are the Concordant Literal New Testament with Keyword Concordance ("CLNT") and the Concordant Version of the Old Testament ("CVOT").  A. E. Knoch designed the Concordant Version in such a way as to put the English reader who lacks a formal knowledge of Koine Greek in possession of all the vital facts of the most ancient codices: Codex Vaticanus, Codex Sinaiticus, and Codex Alexandrinus.  The CPC's efforts yielded a restored Greek text, titled The Concordant Greek Text, containing all of the important variant readings found in the codices mentioned above.  This was done with the intent of conforming, as far as possible, to the original autograph manuscripts.  An utterly consistent hyper-literal sub-linear based upon a standard English equivalent for each Greek element is to be found beneath each Greek word.  The Concordant Greek Text forms the basis of the Concordant Literal New Testament, which is more idiomatic in its English than the hyper-literal sublinear.  The Concordant Literal New Testament and the Concordant Greek Text are linked together and correlated for the English reader by means of an English concordance—the Keyword Concordance—and a complementary list of the Greek elements.

Constantin von Tischendorf: Lobegott Friedrich Constantin (von) Tischendorf (18 January 1815 – 7 December 1874) was a world leading biblical scholar in his time.  In 1844 he discovered the world's oldest and most complete disputed Bible dating from 325, with the complete New Testament not discovered before.  This Bible is called Codex Sinaiticus, after the St. Catherine's Monastery at Mt. Sinai, where Tischendorf discovered it.  The codex can be seen either in the British Library in London, or as a digitalised version on the Internet.  Textual disputes are resolved when the two oldest books, Codex Sinaiticus (source aleph, 4th AD) and Codex Vaticanus (source beta, 4th AD), agree with each other.  Tischendorf was made an Honorary Doctor by Oxford University on 16 March 1865, and an Honorary Doctor by Cambridge University on 9 March 1865 following this find of the century.  While a student gaining his academic degree in the 1840s, he earned international recognition when he deciphered the "Codex Ephraemi Rescriptus", a 5th-century Greek manuscript of the New Testament.

Codex Fuldensis: The Codex Fuldensis, also known as the Victor Codex (Hessian State Library, "Codex Bonifatianus I"), designated by F, is a New Testament manuscript based on the Latin Vulgate made between 541 and 546.  The codex is considered the second most important witness to the Vulgate text; and is also the oldest complete manuscript witness to the order of the Diatessaron.  It is an important witness in any discussion about the authenticity of 1 Corinthians 14:34-35 and the Comma Johanneum.  It is one of the earliest dated manuscripts of the New Testament.  It was corrected until 2 May, 546 AD.

Seven trumpets: Seven trumpets are sounded, one at a time, to cue apocalyptic events that were seen in the vision of the "Revelation of Christ Jesus", by John of Patmos, as written in the Book of Revelation of the New Testament.  The seven trumpets are sounded by seven angels and the events that follow are described in detail from Revelation Chapters 8 to 11.  According to Revelation 8:1-2, the angels sound these trumpets after the breaking of the seventh seal.  These seals secured the apocalyptic document, that was in the right hand of "Him" who sits on the main throne.  The trumpets are referred to in Koine Greek as σάλπιγγος ("salpingos", salpinx); this was a straight, narrow bronze tube with a mouthpiece of bone and a bell; they do not resemble modern trumpets.

Rossano Gospels: The Rossano Gospels, designated by 042 or Σ (in the Gregory-Aland numbering), ε 18 (Soden), at the cathedral of Rossano in Italy, is a 6th-century illuminated manuscript Gospel Book written following the reconquest of the Italian peninsula by the Byzantine Empire.  Also known as Codex purpureus Rossanensis due to the reddish-purple ("purpureus" in Latin) appearance of its pages, the codex is one of the oldest surviving illuminated manuscripts of the New Testament.  The manuscript is famous for its prefatory cycle of miniatures of subjects from the "Life of Christ", arranged in two tiers on the page, sometimes with small Old Testament prophet portraits below, prefiguring and pointing up to events described in the New Testament scene above.

Book of Revelation: The Book of Revelation, often called the Revelation to John, the Apocalypse of John, The Revelation, or simply Revelation or Apocalypse, is a book of the New Testament that occupies a central place in Christian eschatology.  Its title is derived from the first word of the text, written in Koine Greek: "apokalypsis", meaning "unveiling" or "revelation" (before title pages and titles, books were commonly known by their first words, as is also the case of the Hebrew Five Books of Moses (Torah)).  The Book of Revelation is the only apocalyptic document in the New Testament canon (although there are short apocalyptic passages in various places in the Gospels and the Epistles).

Papyrus 75: Papyrus 75 (formula_1, "Papyrus Bodmer XIV-XV") is an early Greek New Testament papyrus.  It is generally described as "the most significant" papyrus of the New Testament to be discovered so far.  This evaluation of the manuscript is a result of the early date that has usually been assigned to it (circa 175-225 CE) and the fact that its text so closely resembles that of the fourth century Codex Vaticanus, but the early date of formula_1, and therefore its importance for the textual criticism of the New Testament, has recently been called into question.

Codex Porphyrianus: Codex Porphyrianus designated by P or 025 (in the Gregory-Aland numbering), α 3 (von Soden), is a Greek uncial manuscript of the Acts of Apostles, Pauline epistles, and General epistles, with some lacunae, dated paleographically to the 9th century.  It is one of a few uncial manuscripts that include the Book of Revelation.

Comparison of codices Sinaiticus and Vaticanus: Codex Sinaiticus and Codex Vaticanus, two of great uncial codices, representatives of the Alexandrian text-type, are considered excellent manuscript witnesses of the text of the New Testament.  Most critical editions of the Greek New Testament give precedence to these two chief uncial manuscripts, and the majority of translations are based on their text.  Nevertheless, there are many differences between these two manuscripts.  According to Dean Burgon: "It is in fact easier to find two consecutive verses in which these two MSS differ the one from the other, than two consecutive verses in which they entirely agree."
