1 Corinthians 14:2,18,19,28

²For he who speaks in another language speaks not to men, but to God; for no one understands; but in the Spirit he speaks mysteries. ¹⁸I thank my God, I speak with other languages more than you all. 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. ²⁸But if there is no interpreter, let him keep silent in the assembly, and let him speak to himself, and to God. 1 Corinthians 14:2,18,19,28
