He was the second abbot of the great monastery of Mount Izla after its founder, Abraham of Kashkar.
[2][3] The biography of Dadishoʿ written by his successor as abbot, Babai the Great, is lost, but it was used as a source for Ishoʿdnaḥ's Book of Chastity (8th century) and Thomas of Marga's Book of Governors (9th century).
[1] In Adiabene, Dadishoʿ was joined by several disciples, including Sahrowai, the future bishop of Arzun.
He moved to the diocese of Marga and lived seven years in the monastery of Risha under Abbot Stephen the Great.
According to Ishoʿdnaḥ, he governed the monastery as rišdayra (leader of the community) for only three months after the death of Abraham in 588.
