20. Brothers, be not children in understanding, howbeit in malice be ye children; but in understanding be perfect.
21. In the law it is written, In other tongues and with other lips I will speak unto this people; and yet for all that, they will not hear me, saith the Lord.
22. Therefore, tongues are for a sign, not to those that believe, but to those that do not believe; but prophecy is not for those that do not believe, but for those who believe.
23. If, therefore, the whole congregation {Gr. ekklesia – called out ones} is 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 ye are mad?
24. But if all prophesy, and there come in one that does not believe or one unlearned, he is convinced of all, he is judged of all;
25. for the secrets of his heart are made manifest; and so falling down on his face, he will worship God, declaring that God is indeed in you.
26. How is it then, brothers? when ye come together, each one of you has a psalm, has doctrine, has tongues, has revelation, has interpretation. Let all things be done unto edification.
27. If anyone speaks in an unknown tongue, let it be by two, or at the most by three, and that by course; and let one interpret.
28. But if there is no interpreter, let him keep silence in the congregation {Gr. ekklesia – called out ones}, and let him speak to himself and to God.
29. Let the prophets speak two or three, and let the others judge.
