This motet by the Spanish composer Andreas de Silva is cast in three sections: Illumina oculos meos à6, Fac mecum à3 and Periit fuga à6.

Translation:

Enlighten my eyes, lest I ever sleep in death,
lest my enemy say to me, I have prevailed against him.
Into your hands, O Lord, I commend my spirit. You have redeemed me, O Lord, God of truth.
I have spoken with my tongue. Make known to me, O Lord, my end.
And the number of my days, that I may know what is lacking to me.
Make a sign for me for good, that those who hate me may see and be ashamed, because you, O Lord, have helped me. You, O Lord
have broken my bonds. I will sacrifice to you a sacrifice of praise and call on the name of the Lord.
My flight has perished, and there is no one who seeks my soul.
I cried out to you, O Lord, and said, You are my hope, my portion in the land of the living. I will confess to you, Lord, all your works, and your saints will bless you.

Text taken from five psalms: XII, 4-5; XXX, 6: LXXXV, 17; CXV, 16-17 and CXLI, 5-6. These are associated with the life of the Benedictine abbott St. Bernhard - a passionate advocate for reform and the emerging Knights Templar. The piece may have been used as a funeral motet.
