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.
Berean Standard Bible
For he that speaketh in an unknown tongue speaketh not unto men, but unto God: for no man understandeth him; howbeit in the spirit he speaketh mysteries.
For he who speaks in another language speaks not to men, but to God, for no one understands, but in the Spirit he speaks mysteries.
