1 Corinthians 14:27-31

If anyone speaks in a tongue, it must be by two or at the most three, and each one in turn, and one is to interpret;

but if there is no interpreter, he is to keep silent in church; and have him speak to himself and to God.

Have two or three prophets speak, and have the others pass judgment.

But if a revelation is made to another who is seated, then the first one is to keep silent.

For you can all prophesy one by one, so that all may learn and all may be exhorted;
