The text translated is the 6th or 7th century Codex Ambrosianus- the oldest complete Semitic Old Testament extant. This volume contains the Minor Prophets: Hosea through Malachi (the last 12 books of the Old testament).
Aramaic was the native language of Jesus and of Israel in the 1st century AD.
This is a literal word for word interlinear translation of the 1900+ year old Aramaic Old Testament called the Peshitta. Read this Gospel translated directly from inspired John's Aramaic words given by Rucha d'Qoodsha (The Spirit of Holiness) presenting The Lord Messiah Yeshua as Jehovah of Hosts- The Living God of Heaven and Creator of the universe, and according to the words which he himself spoke. Mel Gibson's film, The Passion of The Christ presented an Aramaic script for most of the dialogue of Jesus and the Apostles and other Jews, which added realism, historic accuracy and power to the film. The Peshitta has a long tradition among Syrian and Assyrian (Iraqi and Lebanese) Christians as being the original text of the New Testament written by the Apostles and Evangelists of Jesus in the first century AD. Aramaic was the language of Jesus and his countrymen of Israel, as well as that of neighboring Syria, Persia, Asia, and all Jewish colonies throughout the known world. This is the Gospel of John translated from the Aramaic text of the 1905 Syriac Peshitta New Testament, published by the British and United Bible Societies.
