This chant is a kontakion from the akathist to the Intercession of the Theotokos. On October 14 (according to the Gregorian calendar) the Orthodox Church celebrates a great holiday – the Protection of the Mother of God.
The text of the chant:
O all-praised Mother, Most pure Lady, Virgin, Theotokos, to Thee do I lift up the eyes of my soul and body, to Thee do I stretch forth my hands grown feeble and I cry from the depth of my heart: look down on the faith and humility of my soul; shelter me with Thy almighty protection, that I be saved from all assault and distress, and in the hour of my death, be by me, O Thou all-blessed, and deliver me from the torment prepared for me because of my sins, that, venerating Thee, I may ever cry: Alleluia! Alleluia! Alleluia!
