10. It happens that there are many different languages in the world, and none is meaningless;
11. but if I do not know the meaning of a language, I shall be a foreigner to one who speaks it, and one who speaks it a foreigner to me.
12. So with yourselves: since you strive eagerly for spirits, seek to have an abundance of them for building up the church.
13. Therefore, one who speaks in a tongue should pray to be able to interpret.
14. [For] if I pray in a tongue, my spirit is at prayer but my mind is unproductive.
15. So what is to be done? I will pray with the spirit, but I will also pray with the mind. I will sing praise with the spirit, but I will also sing praise with the mind.
16. Otherwise, if you pronounce a blessing [with] the spirit, how shall one who holds the place of the uninstructed say the “Amen” to your thanksgiving, since he does not know what you are saying?
