1 Corinthians 14:21–22

21 In the Law it is written:

“Through men of strange tongues

and through the lips of foreigners

I will speak to this people,

but even then they will not listen to me,”f

says the Lord.

22 Tongues, then, are a sign, not for believers but for unbelievers; prophecy, however, is for believers, not for unbelievers.
