1 Corinthians 14:22-24

International Standard Version

²² Foreign languages, then, are meant to be a sign, not for believers, but for unbelievers, while prophecy is meant, not for unbelievers, but for believers. ²³ Now if the whole church gathers in the same place and everyone is speaking in foreign languages, when uneducated people or unbelievers come in, they will say that you are out of your mind, won’t they? ²⁴ But if everyone is prophesying, when an unbeliever or an uneducated person comes in he will be convicted and examined by everything that’s happening.^[a]
