1 Corinthians 14:29-33

Let the prophets speak two or three, and let the other judge. If any thing be revealed to another that sitteth by, let the first hold his peace. For ye may all prophesy one by one, that all may learn, and all may be comforted. And the spirits of the prophets are subject to the prophets. For God is not the author of confusion, but of peace, as in all churches of the saints.
