I Corinthians 14:27-32

If anyone speaks in a tongue, let there be two or at the most three, each in turn, and let one interpret. But if there is no interpreter, let him keep silent in church, and let him speak to himself and to God. Let two or three prophets speak, and let the others judge. But if anything is revealed to another who sits by, let the first keep silent. For you can all prophesy one by one, that all may learn and all may be encouraged. And the spirits of the prophets are subject to the prophets.
