Let All Things be done unto Edifying

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. 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. 28 But if there be no interpreter, let him keep silence in the church; and let him speak to himself, and to God. 29 Let the prophets speak two or three, and let the other judge. 30 If any thing be revealed to another that sitteth by, let the first hold his peace. 1 Corinthians 14:26-30
