2. The Everlasting Voices

O SWEET everlasting Voices be still;

Go to the guards of the heavenly fold

And bid them wander obeying your will

Flame under flame, till Time be no more;

Have you not heard that our hearts are old,

That you call in birds, in wind on the hill,

In shaken boughs, in tide on the shore?

O sweet everlasting Voices be still.
