1 Corinthians 14:19-21

World English Bible

¹⁹ However in the assembly I would rather speak five words with my understanding, that I might instruct others also, than ten thousand words in another language.

²⁰ Brothers, don’t be children in thoughts, yet in malice be babies, but in thoughts be mature. ²¹ In the law it is written, “By men of strange languages and by the lips of strangers I will speak to this people. They won’t even hear me that way, says the Lord.”Isaiah 28:11-12
