1 Corinthians 14:26-28

What is it then, brethren? When ye come together, each one hath a psalm, hath a teaching, hath a revelation, hath a tongue, hath an interpretation. Let all things be done unto edifying. If any man speaketh in a tongue, let it be by two, or at the most three, and that in turn; and let one interpret: but if there be no interpreter, let him keep silence in the church; and let him speak to himself, and to God.
