1 Corinthians 14:26-31

26What is it then, brethren? whenever ye come together, each [of you] has a psalm, has a teaching, has a tongue, has a revelation, has an interpretation. Let all things be done to edification.

27If any one speak with a tongue, [let it be] two, or at the most three, and separately, and let one interpret;

28but if there be no interpreter, let him be silent in [the] assembly, and let him speak to himself and to 1God.

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

30But if there be a revelation to another sitting [there], let the first be silent.

31For ye can all prophesy one by one, that all may learn and all be encouraged.
