1 Corinthians 14:7-9

International Children’s Bible

⁷ It is the same as with non-living things that make sounds—like a flute or a harp. If different musical notes are not made clear, you will not know what song is being played. Each note must be played clearly for you to be able to understand the tune. ⁸ And in a war, if the trumpet does not sound clearly, the soldiers will not know it is time to prepare for fighting. ⁹ It is the same with you. The words you speak with your tongue must be clear. Unless you speak clearly, no one can understand what you are saying. You will be talking in the air!
