Original Language

The New Testament was probably completely composed in Koine Greek, the language of the earliest manuscripts. Some scholars believe that parts of the Greek New Testament (in particular, the Gospel of Matthew) are actually a translation of an Aramaic or Hebrew original. Of these, a small number accept the Syriac Peshitta as representative of the original. See further Aramaic primacy.

In scholarly writing, ancient translations are frequently referred to as "versions", with the term "translation" being reserved for medieval or modern translations. Bible versions are discussed below, while Bible translations can be found on a separate page.

The original texts of the Tanakh were in Hebrew, although some portions were in Aramaic. In addition to the authoritative Masoretic Text, Jews still refer to the Septuagint, the translation of the Hebrew Bible into Greek, and the Targum Onkelos, an Aramaic version of the Bible.

The primary Biblical text for early Christians was the Septuagint . In addition they translated the Hebrew Bible into several other languages. Translations were made into Syriac, Coptic, Ge'ez and Latin, among other languages. The Latin translations were historically the most important for the Church in the West, while the Greek-speaking East continued to use the Septuagint translation of the Old Testament and had no need to translate the New Testament.

The earliest Latin translation was the Old Latin text, or Vetus Latina, which, from internal evidence, seems to have been made by several authors over a period of time. It was based on the Septuagint, and thus included books not in the Hebrew Bible.
