1 Corinthians 14:26-28

26What should you do then, brothers and sisters? When you come together, each one has a song, has a lesson, has a revelation, has a tongue, has an interpretation. Let all these things be done for the strengthening of the church.

27If someone speaks in a tongue, it should be two, or at the most three, one after the other, and someone must interpret.

28But if there is no interpreter, he should be silent in the church. Let him speak to himself and to God.
