Singing through another snippet from A New Book of Old Hymns
https://newbookoldhymns.brandt.id.au/hymns/requiem.html
Requiem Aeternam, dona eis Domine, et lux perpetua luceat eis. Eternal rest, grant unto them, O Lord, and let perpetual light shine upon them.
This is the introit for the funeral Mass, All Souls Day and Masses of the Dead. The gradual also has the same words, but it more ornate. Great for the month of November.
