Greek

Hebrew texts began to be translated into Greek in Alexandria in about 280 BC and continued until about 130 BC. These early Greek translations – supposedly commissioned by Ptolemy II Philadelphus – were called the Septuagint (Latin for ' Seventy ') from the supposed number of translators involved (hence its abbreviation " LXX "). This Septuagint remains the basis of the Old Testament in the Eastern Orthodox Church.

It varies in many places from the Masoretic Text and includes numerous books no longer considered canonical in some traditions: 1 Esdras, Judith, Tobit, the books of Maccabees, the Book of Wisdom, Sirach, and Baruch. Early modern biblical criticism typically explained these variations as intentional or ignorant corruptions by the Alexandrian scholars, but most recent scholarship holds it is simply based on early source texts differing from those later used by the Masoretes in their work.

The Septuagint was originally used by Hellenized Jews whose knowledge of Greek was better than Hebrew. However, the texts came to be used predominantly by gentile converts to Christianity and by the early Church as its scripture, Greek being the lingua franca of the early Church. The three most acclaimed early interpreters were Aquila of Sinope, Symmachus the Ebionite, and Theodotion; in his Hexapla, Origen placed his edition of the Hebrew text beside its transcription in Greek letters and four parallel translations: Aquila's, Symmachus's, the Septuagint's, and Theodotion's. The so-called "fifth" and "sixth editions" were two other Greek translations supposedly miraculously discovered by students outside the towns of Jericho and Nicopolis: these were added to Origen's Octapla.

In 331, Constantine I commissioned Eusebius to deliver fifty Bibles for the Church of Constantinople. Athanasius recorded Alexandrian scribes around 340 preparing Bibles for Constans. Little else is known, though there is plenty of speculation. For example, it is speculated that this may have provided motivation for canon lists and that Codex Vaticanus and Codex Sinaiticus are examples of these Bibles. Together with the Peshitta and Codex Alexandrinus, these are the earliest extant Christian Bibles. There is no evidence among the canons of the First Council of Nicaea of any determination on the canon. However, Jerome (347–420), in his Prologue to Judith, claims that the Book of Judith was "found by the Nicene Council to have been counted among the number of the Sacred Scriptures".
