Moses Bar-Kepha (born in Balad in Nineveh, now in Iraq, about the year 813; died at the age of ninety, in 903) was a writer and one of the most celebrated bishops of the Syriac Orthodox Church of the ninth century.
A biography of him, written by an anonymous Syriac writer, is preserved in one of the Vatican manuscripts, extracts from which are given by Asemani in his Bibliotheca Orientalis (II, 218f.). He was a monk and afterwards became bishop of three cities, Beth-Ramman, Beth-Kionaya and Mosul on the Tigris, assuming the name of Severus. For ten years he was the patriarchal Periodeutes, or visitor, of the Diocese of Tagrit where he acquired a great fame and reputation. He was buried in the monastery of St. Sergius, situated on the Tigris, near his native city.
