1 Corinthians 14:2
For he who speaks in a tongue does not speak to men, but to God. Indeed, no one understands him; he utters mysteries in the Spirit.

1 Corinthians 14:4
The one who speaks in a tongue edifies himself, but the one who prophesies edifies the church.

1 Corinthians 14:5
I wish that all of you could speak in tongues, but I would rather have you prophesy. He who prophesies is greater than one who speaks in tongues, unless he interprets, so that the church may be edified.

1 Corinthians 14:17
You may be giving thanks well enough, but the other one is not edified.

1 Corinthians 14:19
But in the church, I would rather speak five coherent words to instruct others than ten thousand words in a tongue.
