Come thou words

The words burn deep within
but do not come.
Oh thou flow of endless depth,
come thou gnawing flames
and be quenched in fulfillment.
Oh, would that they would come,
that they would twine and grow.
Come, oh come thou flow!
Race and rush and run!
Climb, tumble and be frantic!
Come thou light and shine,
as I call and shout,
as I name and cry forth.
Tomorrow will come again,
and you'll be gone.
But before you go, come!
Let the words rush and gush
in endless stream.
Crawl and weave, if need be,
but do not stray far.
Duck and dodge, but oh,
come thou river of speech,
come before I fade away!
Oh, what hole thou leaves,
what channels and rivulets inside.
Come tomorrow, shall I be,
shall I know of thine voice?
