Saint Jonah lived a virtuous and holy life. He had two sons who were glorified afterwards for their confession of Orthodoxy during the time of the Iconoclast heresy. After the death of his wife, Saint Jonah withdrew to the Lavra of Saint Sava the Sanctified (December 5), where both his sons earlier had been tonsured as monks. Saint Jonah dwelt at the Lavra until his death in the ninth century. The Lord bestowed upon His saint the gift of healing.
