1 Corinthians 14:9-11

Good News Translation

⁹ In the same way, how will anyone understand what you are talking about if your message given in strange tongues is not clear? Your words will vanish in the air! ¹⁰ There are many different languages in the world, yet none of them is without meaning. ¹¹ But if I do not know the language being spoken, those who use it will be foreigners to me and I will be a foreigner to them.
