1 Corinthians 14:10-12 English Standard Version (ESV)

10. There are doubtless many different languages in the world, and none is without meaning,

11. but if I do not know the meaning of the language, I will be a foreigner to the speaker and the speaker a foreigner to me.

12. So with yourselves, since you are eager for manifestations of the Spirit, strive to excel in building up the church.
