Lyrics
Blessed art thou, O Lord God of our fathers: praised and exalted above all for ever.
Blessed art thou for the Name of thy Majest: praised and exalted above all for ever.
Blessed art thou in the temple of thy holiness:
praised and exalted above all for ever.
Blessed art thou that beholdest the depths, and dwellest between the Cherubim: praised and exalted above all for ever.
Blessed art thou on the glorious throne of thy kingdom: praised and exalted above all for ever.
Blessed art thou in the firmament of heaven: praised and exalted above all for ever.
Glory be to the Father, and to teh Son, and to the Holy Ghost; as it was in the beginning, is now, and ever shall be, world without end. Amen.
