1 Corinthians 14:18
Verse 18 of 40. The 14th of 16 chapters in 1 Corinthians, in The Letters of Paul.
14For if I pray in another language, my spirit prays, but my understanding is unfruitful.
15What should I do? I will pray with the spirit, and I will pray with the understanding also. I will sing with the spirit, and I will sing with the understanding also.
16Otherwise, if you bless with the spirit, how will he who fills the place of the unlearned say the “Amen” at your giving of thanks, seeing he doesn’t know what you say?
17For you most certainly give thanks well, but the other person is not built up.
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.
20Brothers, don’t be children in thoughts, yet in malice be babies, but in thoughts be mature.
21In 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 listen to me that way, says the Lord.”
22Therefore other languages are for a sign, not to those who believe, but to the unbelieving; but prophesying is for a sign, not to the unbelieving, but to those who believe.
