1 Corinthians 14:9

Douay-Rheims version of The Bible - 1752 version

So likewise you, except you utter by the tongue plain speech, how shall it be known what is said? For you shall be speaking into the air.

See the chapter Copy

I therefore so run, not as at an uncertainty: I so fight, not as one beating the air:

There are, for example, so many kinds of tongues in this world; and none is without voice.
