1 Corinthians 14:7-9

EasyEnglish Bible

⁷ Think about how people make music with flutes or harps. Those things are not alive. We have to use them to make clear sounds. If we do not use them properly, then nobody can recognize the music. ⁸ Soldiers will not prepare to fight unless they hear a clear sound from the trumpet.

⁹ It is the same for you. You must use your tongue to speak clearly. If not, nobody will understand what you are saying. You will only be speaking words into the air.
