1 Corinthians 14:12-13

14:12 It is the same with you. Since you are eager for manifestations of the Spirit, seek to abound in order to strengthen the church.

14:13 So then, one who speaks in a tongue should pray that he may interpret.

1 Corinthians 14:26-28

Church Order

14:26 What 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. 14:27 If someone speaks in a tongue, it should be two, or at the most three, one after the other, and someone must interpret. 14:28 But if there is no interpreter, he should be silent in the church. Let him speak to himself and to God.
