1 Corinthians 14:20-22

Revised Geneva Translation

²⁰ Brothers, do not be children in understanding, but concerning wickedness be children; in understanding be of a ripe age.

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.
