1 Corinthians 14:23-25

Darby Translation

²³ If therefore the whole assembly come together in one place, and all speak with tongues, and simple [persons] enter in, or unbelievers, will not they say ye are mad?

²⁴ But if all prophesy, and some unbeliever or simple [person] come in, he is convicted of all, he is judged of all;

²⁵ the secrets of his heart are manifested; and thus, falling upon [his] face, he will do homage to God, reporting that God is indeed amongst you.
