1 Corinthians 14:21-23

Revised Geneva Translation

²¹ In the Law it is written, “‘By other tongues, and by other languages, will I speak to this people. Yet so shall they not hear me’, says the Lord.”

²² Therefore, tongues are for a sign, not to those who believe, but to those who do not believe. And prophesying is not for unbelievers, but for believers.

²³ If therefore, when the whole Church comes together as one, and all speak tongues, and there come in those who are unlearned, or those who do not believe, will they not say that you are out of your wits?
