Thomas of Harqel explained

Thomas of Harqel was a miaphysite bishop from the early 7th century. Educated in Greek at the monastery of Qenneshre, he became bishop of Mabbug in Syria. He was deposed as bishop by the anti-miaphysite metropolitan Domitian of Melitene before 602.^[1] He and Paul of Tella lived as exiles in the Coptic monastery of the Enaton near Alexandria, Egypt. At the request of Athanasios I, they worked on a Syriac translation of the Greek Bible. Translation of the New Testament, known as the Harclensis was completed in 616.^{[2] [3] [4]} At this time, 2 Peter, 2 John, 3 John, Jude and Revelation were added to the Syriac Bible. Until then they were excluded.
