1 Corinthians 14:14

Modern King James Version

For if I pray in a tongue, my spirit prays, but my mind is unfruitful.

See the chapter Copy

So then he speaking in a language, let him pray that he may interpret.

yet in a church I desire to speak five words with my mind, so that I might also teach others, than ten thousand words in a tongue.

For he who speaks in a tongue does not speak to men but to God. For no one hears, but in spirit he speaks mysteries.
