1 Corinthians 14:27-30

If any speak in a tongue, let there be only two or at most three, and each in turn, and let someone interpret. But if there is no one to interpret, let each of them keep silent in church and speak to himself and to God. Let two or three prophets speak, and let the others weigh what is said. If a revelation is made to another sitting there, let the first be silent.
