Here's one from the early 1800's
The Power of Words
'Tis a strange mystery, the power of words!
Life is in them, and death.
A word can send
The crimson colour hurrying to the cheek.
Hurrying with many meanings;
or can turn
The current cold and deadly
to the heart.
Anger and fear are in them;
grief and joy
Are on their sound;
yet slight, impalpable:--
A word is but a breath
of passing air.
