1 Corinthians 14:17-19

New Revised Standard Version, Anglicised

¹⁷ For you may give thanks well enough, but the other person is not built up. ¹⁸ I thank God that I speak in tongues more than all of you; ¹⁹ 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.
