Irmos: Having traversed the water as though it were dry land, and escaped the evil of Egypt, the Israelite cried aloud: Let us chant unto our Deliverer and God!
By thy supplications, O blessed Isidore, martyr of Christ, grant me enlightenment and grace from heaven, that I may praise thine honored festival.
Theotokion: Having truly given birth to Him Who is God by nature, thou, the pure Theotokos, dost truly hear the angel’s call, bearing Him in both natures in thy divine birthgiving.
Possessed of a perfect heart and soul, and having acquired a blameless life, O martyr Isidore, thou didst struggle well with the martyrs for God.
Having ordered thy life according to the law, O martyr Isidore, thou didst keep the Faith of salvation unadulterated, like a treasure which cannot be stolen away, O most blessed one.
