21. It is written in the law, By people of other tongues, and by strange lips, will I speak to this people; and neither thus will they hear me, saith the Lord.
22. So that tongues are for a sign, not to those who believe, but to unbelievers; but prophecy, not to unbelievers, but to those who believe.
23. If therefore the whole assembly come together in one place, and all speak with tongues, and simple persons enter in, or unbelievers, will not they say ye are mad?
24. But if all prophesy, and some unbeliever or simple person come in, he is convicted of all, he is judged of all;
25. the secrets of his heart are manifested; and thus, falling upon his face, he will do homage to God, reporting that God is indeed amongst you.
26. What is it then, brethren? whenever ye come together, each of you has a psalm, has a teaching, has a tongue, has a revelation, has an interpretation. Let all things be done to edification.
27. If any one speak with a tongue, let it be two, or at the most three, and separately, and let one interpret;
28. but if there be no interpreter, let him be silent in the assembly, and let him speak to himself and to God.
29. And let two or three prophets speak, and let the others judge.
30. But if there be a revelation to another sitting there, let the first be silent.
31. For ye can all prophesy one by one, that all may learn and all be encouraged.
