The name 'Esdras' is found in the title of four texts (entitled Ezra, Nehemiah, 1 Esdras, 2 Esdras in most English versions) attributed to, or associated with, the prophet Ezra. The naming convention of the four books of Esdras differs between church traditions; and has changed over time. Esdras () is a Greco-Latin variation of the Hebrew name 'Ezra' (עזרא). The books associated with Ezra are titled differently in different versions of the Bible. The following table summarizes the various names: The Thirty-nine Articles that define the doctrines of the Church of England follow the naming convention of the Clementine Vulgate. Likewise, the Vulgate enumeration is often used by modern scholars, who nevertheless use the name Ezra to avoid confusion with the Greek and Slavonic enumerations: 1 Ezra (Ezra), 2 Ezra (Nehemiah), 3 Ezra (Esdras A/1 Esdras), 4 Ezra (chapters 3–14 of 4 Esdras), 5 Ezra (chapters 1–2 of 4 Esdras) and 6 Ezra (chapters 15–16 of 4 Esdras). Otherwise, modern scholars sometimes apply the term 'Greek Esdras' for 3 Ezra, and 'Latin Esdras' for 4 Ezra, 5 Ezra and 6 Ezra together. The two books universally considered canonical, Ezra and Nehemiah (lines 1 and 2 of the table above), originated in the Hebrew bible as one book titled Ezra (= Esdras). Otherwise, however, early Christian citations of the 'Book of Ezra' without qualification commonly denote the alternative Greek translation of Ezra represented by 1 Esdras; so that when early Christian writers talk of 'two books of Ezra', it is 1 Esdras and Ezra–Nehemiah that are being identified, and surviving Old Latin biblical manuscripts include both books in that order as the "first" and "second" books of Ezra. In the Greek canon, and in all surviving early Greek pandect bibles, 1 Esdras and Ezra–Nehemiah are termed Esdras A and Esdras B respectively. For Ambrose 1 Esdras was the 'first book of Esdras', Ezra–Nehemiah was the 'second book of Esdras', and 2 Esdras was the 'third book of Esdras'.
