2 Esdras 2 Esdras (also called 4 Esdras, Latin Esdras, or Latin Ezra) is the name of an apocalyptic book in many English versions of the Bible (see "Naming conventions" below). Its authorship is ascribed to Ezra. It is reckoned among the apocrypha by Roman Catholics, Protestants, and most Eastern Orthodox Christians. Although Second Esdras was preserved in Latin as an appendix to the Vulgate and passed down as a unified book, it is generally considered to be a tripartite work.
