1 Corinthians 14:29-33

29And let the prophets speak by two or three, and let the others discern.

30But if a revelation be made to another sitting by, let the first keep silence.

31For ye all can prophesy one by one, that all may learn, and all may be comforted;

32and the spirits of the prophets are subject to the prophets;

33for God is not a God of confusion, but of peace; as in all the churches of the saints.
