1 Corinthians 14:22-24

New Matthew Bible

²² Therefore tongues are for a sign, not to those who believe, but to those who believe not. On the other hand, prophesying serves not for those who don’t believe, but for those who believe.

²³ If, therefore, when all the congregation has come together and all speak with tongues, there come in people who are unlearned, or those who do not believe, will they not say that you are out of your minds? ²⁴ But if all prophesy and there comes in one who does not believe, or one unlearned, he is convicted by everyone, and is judged by everyone.
