blasphemous or empty

Ring out the bells, make the air heavy with them!
Send out fog of myrrh, heady spice! Earthly delight!
Choke on that, the fervor, you may sing your battle cry;
you may,
you may,
you may lift it to the raven wind,
you may,
or tune your voice to smaller hymns you may,
to thank the hearth, next the bread, last the LORD;
that is your song.

You may sing the trees, make them greener in note and phrase
than ever they were in golden summer light;
sing that light,
sing the Song! Use your voice,
warble like a thrush,
a hen at creaking day, a creek--
sing the creek! Sing it colder and faster,
sing it down to sea-green shores, misted wharves,
sing it past the lonesome tottering hermit--
sing the sands, sing their distraction.

Sing the large hymns, not the small.
Sing first the LORD;
that is to sing the world.
