Irmos: I heard report of Thy power, and my heart was filled with gladness in the Lord.
As thou didst show forth thy life on earth as angelic, thou joinest chorus with the heavenly hosts.
Theotokion: O Theotokos, now as ever free thy servants from the iniquitous foe by thy supplications.
Having first been a leader of monks from the desert, O divinely wise and glorious one, thou didst provide a model for those in the city.
Thy memory now doth truly gladden the hearts of those who hymn thee, O father Isaacius.
