Moses, also called Abba Musa, was the Coptic bishop of Awsīm (or Wasīm) in Giza from about 735 until after 767. He was an influential churchman in Islamic Egypt. Moses was a monk before he became a bishop. His predecessor, Gamul, was bishop about 728 and Moses had succeeded by about 735. He was a companion of the Patriarch Michael I. When in 743 there was a deadlock between northern and southern factions in the election of a new Patriarch of Alexandria, Moses successfully put forward Michael as a compromise. His influence probably stemmed in part from his proximity to the Egyptian government in Fustat.
