1 Corinthians 14:18-21

I thank God that I speak in tongues more than all of you. Nevertheless, in church I would rather speak five words with my mind in order to instruct others, than ten thousand words in a tongue. Brothers, do not be children in your thinking. Be infants in evil, but in your thinking be mature. In the Law it is written, “By people of strange tongues and by the lips of foreigners will I speak to this people, and even then they will not listen to me, says the Lord.”
