Деяния святых апостолов
The original order of books was: Pauline epistles, Acts of the Apostles, Catholic epistles, Revelation of John, Gospels. The Pauline epistles precede Acts of the Apostles (like in Codex Sinaiticus). This order was changed by a binder: Gospels, Pauline epistles, Acts, Catholic epistles, and Apocalypse.
