But now, brothers, if I come to you speaking with other languages, what would I profit you unless I speak to you either by way of revelation, or of knowledge, or of prophesying, or of teaching?
Even lifeless things that make a sound, whether pipe or harp, if they didn’t give a distinction in the sounds, how would it be known what is piped or harped?
For if the trumpet gave an uncertain sound, who would prepare himself for war?
So also you, unless you uttered by the tongue words easy to understand, how would it be known what is spoken?
For you would be speaking into the air.
