1 Corinthians 14:29KJV

27If any man speak in an tongue, by two, or at the most three, and by course; and let one interpret.

28But if there be no interpreter, let him keep silence in the church; and let him speak to himself, and to God.

29Let the prophets speak two or three, and let the other judge.

30If be revealed to another that sitteth by, let the first hold his peace.

31For ye may all prophesy one by one, that all may learn, and all may be comforted.
