In finem, in carminibus. Psalmus David. Pro octava.
Unto the end, in verses, a psalm for David, for the octave.
- For the octave: That is, to be sung on an instrument of eight strings. St. Augustine understands it mystically, of the last resurrection, and the world to come; which is, as it were, the octave, or eighth day, after the seven days of this mortal life: and for this octave, sinners must dispose themselves, like David, by bewailing their sins, whilst they are here upon earth.
