domine, attende et miserere, domine deus meus,
lux caecorum et virtus infirmorum
statimque lux videntium et virtus fortium,
attende animam meam et audi clamantem de profundo.
Lord, hear me and have mercy. Lord my God,
you are the light of the blind and the strength of the weak,
as well as the light of the sighted and the strength of the powerful.
Attend to my soul, and hear the one crying from the depths.
~ Augustine, Confessions 11,2
