1 Corinthians 14:7-9

Common English Bible

⁷ Likewise, things that aren’t alive like a harp or a lyre can make a sound, but if there aren’t different notes in the sounds they make, how will the tune from the harp or the lyre be recognized? ⁸ And if a trumpet call is unrecognizable, then who will prepare for battle? ⁹ It’s the same way with you: If you don’t use language that is easy to understand when you speak in a tongue, then how will anyone understand what is said?
