1 Corinthians 14:6-8

EHV Bible

⁶ Brothers,^[a] if I come to you speaking in tongues, what good will I do you, unless I communicate to you a revelation, or some knowledge, or a prophecy, or some teaching? ⁷ Even lifeless instruments that produce sound, such as a flute or a harp, if they do not make the notes distinct from one another, how will anyone know what is being played on the flute or harp? ⁸ If the trumpet makes an uncertain sound, who will get ready for battle?
