I Corinthians 14:26-28

How is it then, brethren? Whenever you come together, each of you has a psalm, has a teaching, has a tongue, has a revelation, has an interpretation. Let all things be done for edification. If anyone speaks in a tongue, let there be two or at the most three, each in turn, and let one interpret. But if there is no interpreter, let him keep silent in church, and let him speak to himself and to God.
