1-Corinthians 14:23 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 ye are mad?
14:24 But if all prophesy, and there come in one that believeth not, or one unlearned, he is convinced of all, he is judged of all:
14:25 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.
14:26 How is it then, brethren? when ye come together, every one of you hath a psalm, hath a doctrine, hath a tongue, hath a revelation, hath an interpretation. Let all things be done unto edifying.
14:27 If any man speak in an unknown tongue, let it be by two, or at the most by three, and that by course; and let one interpret.
14:28 But if there be no interpreter, let him keep silence in the church; and let him speak to himself, and to God.
14:29 Let the prophets speak two or three, and let the other judge.
14:30 If any thing be revealed to another that sitteth by, let the first hold his peace.
14:31 For ye may all prophesy one by one, that all may learn, and all may be comforted.
