1 Esdras

1 Esdras (Ancient Greek: Ἔσδρας Αʹ), also Esdras A, Greek Esdras, Greek Ezra, or 3 Esdras, is the ancient Greek Septuagint version of the biblical Book of Ezra in use within the early church and among many modern Christians with varying degrees of canonicity. 1 Esdras is substantially similar to the standard Hebrew version of Ezra–Nehemiah, with the passages specific to the career of Nehemiah removed or re-attributed to Ezra, and some additional material.

As part of the Septuagint translation, it is now regarded as canonical in the churches of the East, but apocryphal in the West; either presented in a separate section or excluded altogether. 1 Esdras is found in Origen's Hexapla. The Greek Septuagint, the Old Latin bible and related bible versions include both Esdras Αʹ (English title: 1 Esdras) and Esdras Βʹ (Ezra–Nehemiah) as separate books.

There is scope for considerable confusion with references to 1 Esdras. The name refers primarily to translations of the original Greek 'Esdras A'. The Septuagint calls it Esdras A, and the Vetus Latina calls it 1 Esdras, while the Vulgate calls it 3 Esdras. It was considered apocryphal by Jerome.
