And even things without life giving sound, whether pipe or harp, except they give a distinction in the sounds, how shall it be known what is piped or harped? {sounds: or, tunes}

For if the trumpet give an uncertain sound, who shall prepare himself to the battle?

There are, it may be, so many kinds of voices in the world, and none of them {is} without signification.

Therefore if I know not the meaning of the voice, I shall be unto him that speaketh a barbarian, and he that speaketh {shall be} a barbarian unto me.
