1 Corinthians 14:27-31 King James Version (KJV)
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.
31 For ye may all prophesy one by one, that all may learn, and all may be comforted.
