21 In the law it is written: “With men of other tonguesand other lipsI will speak to this people;but even then they will not hear Me,”says the Lord.
22 So tongues are for a sign, not to believers, but to unbelievers. But prophesying does not serve unbelievers, but believers.
23 Therefore if the whole church assembles in one place and all speak with tongues, and those who are unlearned or unbelievers come in, will they not say that you are out of your mind?
24 But if all prophesy and there comes in one who does not believe or one unlearned, he is convinced by all and judged by all.
25 Thus the secrets of his heart are revealed. And so falling down on his face, he will worship God and report that God is truly among you.
26 How is it then, brothers? When you come together, every one of you has a psalm, a teaching, a tongue, a revelation, and an interpretation. Let all things be done for edification.
27 If anyone speaks in an unknown tongue, let it be by two, or at the most by three, and each in turn, and let one interpret.
