1 Corinthians 14:20-22

Darby Translation

²⁰ Brethren, be not children in [your] minds, but in malice be babes; but in [your] minds be grown [men].

²¹ It is written in the law, By people of other tongues, and by strange lips, will I speak to this people; and neither thus will they hear me, saith the Lord.

²² So that tongues are for a sign, not to those who believe, but to unbelievers; but prophecy, not to unbelievers, but to those who believe.
