Maire Brennan - Bi Thusa Mo ShuIla (Be Thou My Vision) Lyrics

be thou my vision, o Lord of my heart;
naught be all else to me, save that thou art, -
thou my best thought, in the day and the night,
waking or sleeping, thy presence my light.

be thou my wisdom, be thou my true word;
I ever with thee, and thou with me Lord;
be thou my breastplate, my sword for the fight,
be thou my armour, and be thou my might.
