1 Corinthians 14:12, 13, 26-28

So it is with you. Since you are eager for gifts of the Spirit, try to excel in those that build up the church.

For this reason the one who speaks in a tongue should pray that they may interpret what they say.

What then shall we say, brothers and sisters? When you come together, each of you has a hymn, or a word of instruction, a revelation, a tongue or an interpretation. Everything must be done so that the church may be built up. If anyone speaks in a tongue, two—or at the most three—should speak, one at a time, and someone must interpret. If there is no interpreter, the speaker should keep quiet in the church and speak to himself and to God.
