From Cantiones Sacrae I, 1589. The piece has been transposed up a minor third from the original pitch (A.T.T.B.B.).

Lyrics: Mark ch.13 v.35-37

Vigilate, nescitis enim quando dominus domus veniat, sero, an media nocte, an gallicantu, an mane.
Vigilate ergo, ne cum venerit repente, inveniat vos dormientes.
Quod autem dico vobis, omnibus dico: vigilate.

Watch ye therefore: for ye know not when the master of the house cometh, at even, or at midnight, or at the cockcrowing, or in the morning:
Lest coming suddenly he find you sleeping.
And what I say unto you I say unto all, Watch.
