8. And if the bugle gives an indistinct sound, who will get ready for battle?
9. Similarly, if you, because of speaking in tongues, do not utter intelligible speech, how will anyone know what is being said? For you will be talking to the air.
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.
