10There are, it may be, so many kinds of voices in the world, and none of them is without meaning.
11If then I don`t know the meaning of the voice, I would be to him who speaks a foreigner, and he who speaks will be a foreigner to me.
12So also you, since you are zealous for spiritual gifts, seek that you may abound to the building up of the assembly.
13Therefore let him who speaks in another language pray that he may interpret.
14For if I pray in another language, my spirit prays, but my understanding is unfruitful.
15What is it then? I will pray with the spirit, and I will pray with the understanding also. I will sing with the spirit, and I will sing with the understanding also.
16Else if you bless with the spirit, how will he who fills the place of the unlearned say the "Amen" at your giving of thanks, seeing he doesn`t know what you say?
