1 Corinthians 14:26-31

26How is it then, brethren? when ye are assembled, each one of you hath a psalm, hath a doctrine, hath a tongue, hath a revelation, hath an interpretation. Let all things be done for edification. 27If any man speaketh in an unknown tongue, let it be by two, or at the most by three, and that by course; and let one interpret.1 28But if there is 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 others judge. 30If any thing is revealed to another that sitteth by, let the first hold his peace. 31For ye may all prophesy one by one, that all may learn, and all may be comforted.
