Irmos: Thou art my strength, O Lord, Thou art my power; Thou art my God, Thou art my joy, Who, without leaving the bosom of the Father, hast visited our lowliness. Wherefore, with the Prophet Habbakuk I cry unto Thee: Glory to Thy power, O Thou Who lovest mankind!
Having the Word dwelling wholly within thee, as an invincible warrior thou didst put to shame the pride of the tyrant, and having won victory for His sake, O blessed one, thou hast received from God an imperishable crown, O most glorious martyr Isidore.
Theotokion: He Who became incarnate reneweth all of man, O all-pure one, having united Himself to him without leaving the bosom of the Father; and it was His will to make His abode within thy womb. And, having beggared Himself voluntarily, He hath enriched the world with a wealth of loving-kindness and divinity.
Like a youth thou didst put thine enemies to flight and didst break them asunder, O Isidore, protected by the awesome weapon of the Cross and girded about with might; and thou didst destroy those who hated thee, crying: Glory to Thy power, O Thou Who lovest mankind!
Following the death of the Master, thou didst endure sufferings for His sake; wherefore, the Lord of glory vouchsafed thee life incorruptible, O martyr. And into His hands didst thou commit thy soul, O all-blessed Isidore.
