1 Corinthians 14:6,19

⁶But now, brothers, if I come to you speaking with other languages, what would I profit you, unless I speak to you either by way of revelation, or of knowledge, or of prophesying, or of teaching? ¹⁹However 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. 1 Corinthians 14:6,19
