1 Corinthians 14:19

New King James Version

yet in the church I would rather speak five words with my understanding, that I may teach others also, than ten thousand words in a tongue.

See the chapter Copy

that you may know the certainty of those things in which you were instructed.

I thank my God I speak with tongues more than you all;

Brethren, do not be children in understanding; however, in malice be babes, but in understanding be mature.

He who speaks in a tongue edifies himself, but he who prophesies edifies the church.
