1 Corinthians 14:8-10

International Children’s Bible

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! ¹⁰ It is true that there are many kinds of speech in the world. And they all have meaning.
