Therefore, if I do not know the meaning of the language, I will be a barbarian to the one who is speaking, and the one who is speaking [will be] a barbarian in my [judgment].

But now, brothers, if I come to you speaking with tongues, how do I benefit you, unless I speak to you either with a revelation or with knowledge or with a prophecy or with a teaching?

And so you through the tongue, unless you produce a clear message, how will it be known what is spoken? For you will be speaking into the air.

I am speaking as to sensible [people]; you judge what I am saying.

Now I am not speaking about your own conscience, but the [conscience] of the other [person]. For why [is] my freedom judged by another's conscience?

Therefore I make known to you that no one speaking by the Spirit of God says, "Jesus [is] accursed," and no one is able to say "Jesus [is] Lord" except by the Holy Spirit.

So then, my brothers, desire to prophesy, and do not prevent speaking with tongues.
