Dormition of the Most Holy Theotokos + August 15
--from The Lamentations at the Bier of the Mother of God, Tone 5
O thou most Holy Virgin, who knew not wedlock, the heavens rejoice in thy glorious falling asleep, the hosts of angels are glad, and the whole earth crieth out in joy, singing to thee the funeral song, O Mother of the Lord of all, thou who hast delivered human kind from its ancestral condemnation.
