1 Corinthians 14:27

But if all prophesy, and someone unbelieving or unlearned comes in, he is reproved by all, and he is judged by all.

And thus the secrets of his heart are revealed. So he will fall down on his face and worship God, declaring that God is among you indeed.

What is it then, brothers? When you come together, each one of you has a psalm, has a teaching, has a revelation, has another language, or has an interpretation. Let all things be done to build each other up.

But if there is no interpreter, let him keep silent in the assembly, and let him speak to himself and to God.

Let two or three of the prophets speak, and let the others discern.

But if a revelation is made to another sitting by, let the first keep silent.
