1 Corinthians 14:6-14

6Brothers and sisters, it wouldn’t do you any good if I came to you speaking in other languages, unless I explained revelation, knowledge, prophecy, or doctrine to you.

7Musical instruments like the flute or harp produce sounds. If there is no difference in the notes, how can a person tell what tune is being played?

8For example, if the trumpet doesn’t sound a clear call, who will get ready for battle?

9In the same way, if you don’t speak in a way that can be understood, how will anyone know what you’re saying? You will be talking into thin air.

10No matter how many different languages there are in the world, not one of them is without meaning.

11If I don’t know what a language means, I will be a foreigner to the person who speaks it and that person will be a foreigner to me.

12In the same way, since you’re eager to have spiritual gifts, try to excel in them so that you help the church grow.

13So the person who speaks in another language should pray for an interpretation of what he says.

14If I pray in another language, my spirit prays, but my mind is not productive.
