Monk and spiritual teacher. Born in Beth ʿEdraye, near [
Mosul
](https://gedsh.bethmardutho.org/Mosul), he became a
monk of the [
Monastery of Rabban Hormizd
](https://gedsh.bethmardutho.org/Hormizd-Monastery-of-Rabban), but subsequently moved to the
monastery of Abraham, of Beth Ṣayyare (in the ʿAmadiyya region, N. Iraq).
His Life was written by his disciple Yoḥannan bar Kaldun; this not only
incorporates much of his spiritual teaching (in chapter 8), but it also
gives a detailed picture of monastic life of the time.
