3. On the other hand, one who prophesies does speak to human beings, for their building up, encouragement, and solace.
4. Whoever speaks in a tongue builds himself up, but whoever prophesies builds up the church.
5. Now I should like all of you to speak in tongues, but even more to prophesy. One who prophesies is greater than one who speaks in tongues, unless he interprets, so that the church may be built up.
6. Now, brothers, if I should come to you speaking in tongues, what good will I do you if I do not speak to you by way of revelation, or knowledge, or prophecy, or instruction?
7. Likewise, if inanimate things that produce sound, such as flute or harp, do not give out the tones distinctly, how will what is being played on flute or harp be recognized?
8. And if the bugle gives an indistinct sound, who will get ready for battle?
9. Similarly, if you, because of speaking in tongues, do not utter intelligible speech, how will anyone know what is being said? For you will be talking to the air.
10. It happens that there are many different languages in the world, and none is meaningless;
11. but if I do not know the meaning of a language, I shall be a foreigner to one who speaks it, and one who speaks it a foreigner to me.
12. So with yourselves: since you strive eagerly for spirits, seek to have an abundance of them for building up the church.
13. Therefore, one who speaks in a tongue should pray to be able to interpret.
