1 Corinthians 14:19

King James 3 - The Literal Traslation

But in an assembly I desire to speak five words with my mind, that I may also instruct others, than myriads of words in a foreign language.

See the chapter Copy

that you may know the certainty concerning the words which you were taught.

I thank my God that I speak more languages than all of you.

Brothers, do not be children in your minds, but in malice act like children, and in your minds be mature.

The one speaking in a langusge builds himself up, but he prophesying builds up an assembly.
