1 Corinthians 14:7

5 I wish that all of you could speak in tongues, but I would rather have you prophesy. He who prophesies is greater than one who speaks in tongues, unless he interprets so that the church may be edified.

6 Now, brothers, if I come to you speaking in tongues, how will I benefit you, unless I bring you some revelation or knowledge or prophecy or teaching?

Even in the case of lifeless instruments, such as the flute or harp, how will anyone recognize the tune they are playing unless the notes are distinct?

8 Again, if the trumpet sounds a muffled call, who will prepare for battle?

9 So it is with you. Unless you speak intelligible words with your tongue, how will anyone know what you are saying? You will just be speaking into the air.

Do read the surrounding verses too, because the context often says more than a single verse.
