1 Corinthians 14:9-11

Contemporary English Version

⁹ This is how it is when you speak unknown languages. If no one can understand what you are talking about, you will only be talking to the wind. ¹⁰ There are many different languages in this world, and all of them make sense. ¹¹ But if I don't understand the language that someone is using, we will be like foreigners to each other.
