18. I thank my God, I speak with tongues more than you all:
19. Yet in the church I had rather speak five words with my understanding, that by my voice I might teach others also, than ten thousand words in an unknown tongue.
20. Brethren, be not children in understanding: but in malice be children, but in understanding be men.
21. In the law it is written,
22. Therefore tongues are for a sign, not to them that believe, but to them that believe not: but prophesying serves not for them that believe not, but for them that believe.
23. If therefore the whole church be come together into one place, and all speak with tongues, and there come in those that are unlearned, or unbelievers, will they not say that you are mad?
24. But if all prophesy, and there come in one that believes not, or one unlearned, he is convicted of all, he is judged of all:
25. And thus are the secrets of his heart made manifest; and so falling down on his face he will worship God, and report that God is in you of a truth.
26. How is it then, brethren? when you come together, every one of you has a psalm, has a doctrine, has a tongue, has a revelation, has an interpretation. Let all things be done unto edifying.
27. If any man speak in an unknown tongue, let it be by two, or at the most by three, and that in turn; and let one interpret.
28. But if there be no interpreter, let him keep silence in the church; and let him speak to himself, and to God.
29. Let the prophets speak two or three, and let the others judge.
30. If anything be revealed to another that sits by, let the first hold his peace.
31. For you may all prophesy one by one, that all may learn, and all may be comforted.
32. And the spirits of the prophets are subject to the prophets.
33. For God is not the author of confusion, but of peace, as in all churches of the saints.
