1 Corinthians 14:28-30

Living Bible

²⁸ But if no one is present who can interpret, they must not speak out loud. They must talk silently to themselves and to God in the unknown language but not publicly.

^29-30 Two or three may prophesy, one at a time, if they have the gift, while all the others listen. But if, while someone is prophesying, someone else receives a message or idea from the Lord, the one who is speaking should stop.
