Introit Lyrics

Aeternam dona eis, Domine:
Et lux perpetua luceat eis,
Et lux perpetua luceat eis.

Te decet hymnus, Deus, in Sion,
Et tibi reddetur votum in Jerusalem:
Et lux perpetua luceat eis,
Et lux perpetua luceat eis.

Et lux perpetua luceat eis,
Et lux perpetua luceat eis.

...a luceat eis...
