1 Corinthians 14:8-10

New English Translation

⁸ If, for example, the trumpet makes an unclear sound, who will get ready for battle? ⁹ It is the same for you. If you do not speak clearly with your tongue, how will anyone know what is being said? For you will be speaking into the air. ¹⁰ There are probably many kinds of languages in the world, and none is without meaning.
