1 Corinthians 14:4-11

4One who speaks in a tongue builds up himself, but one who prophesies builds up the community.

5Now I want you all to speak in tongues, but even more that you would prophesy. One who prophesies is greater than one who speaks in tongues—unless he interprets, so that the community may be built up.

6But now, brothers and sisters, if I come to you speaking in tongues, how will I benefit you—unless I speak to you by way of revelation or knowledge or prophecy or teaching?

7It is the same for lifeless things that make a sound—like a flute or a harp. If they make no distinction in the tones, how will what is played be recognized?

8For if the trumpet makes an unclear sound, who will prepare himself for battle?

9So also with you with your tongue—unless you utter speech that is intelligible, how will what is spoken be understood? For you will be talking to the wind!

10It may be that there are many kinds of languages in the world—and none without meaning.

11If then I do not understand the meaning of the language, I will be a foreigner to the speaker, and the speaker will be a foreigner to me.
