1 Corinthians 14:19

New Revised Standard Version Updated Edition 2021

nevertheless, in church I would rather speak five words with my mind, in order to instruct others also, than ten thousand words in a tongue.

See the chapter Copy

so that you may have a firm grasp of the words in which you have been instructed.

I thank God that I speak in tongues more than all of you;

Brothers and sisters, do not be children in your thinking; rather, be infants in evil, but in thinking be adults.

Those who speak in a tongue build up themselves, but those who prophesy build up the church.
