1 Corinthians 14:8-10

Douay-Rheims 1899 American Edition

⁸ For if the trumpet give an uncertain sound, who shall prepare himself to the battle?

⁹ 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.

¹⁰ There are, for example, so many kinds of tongues in this world; and none is without voice.
