1 Corinthians 14:12-14 New International Version Anglicized (NIVUK)

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

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

14. For if I pray in a tongue, my spirit prays, but my mind is unfruitful.
