23If 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? 24But if all prophesy, and there come in one that believeth not, or one unlearned, he is convinced of all, he is judged of all: 25And 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. 26How 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.27If 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. 28But if there be no interpreter, let him keep silence in the church; and let him speak to himself, and to God. 29Let the prophets speak two or three, and let the other judge.
