'Speaking' in the Bible

Or is he not surely speaking for our benefit? It was written for us, because the one plowing and threshing ought to work in hope of enjoying the harvest.

I am speaking to thoughtful people. Consider what I say.

So I want you to understand that no one speaking by the Spirit of God says, "Jesus is cursed," and no one can say, "Jesus is Lord," except by the Holy Spirit.

For the one speaking in a tongue does not speak to people but to God, for no one understands; he is speaking mysteries by the Spirit.

Now, brothers and sisters, if I come to you speaking in tongues, how will I help you unless I speak to you with a revelation or with knowledge or prophecy or teaching?

It is the same for you. If you do not speak clearly with your tongue, how will anyone know what is being said? For you will be speaking into the air.

And if someone sitting down receives a revelation, the person who is speaking should conclude.

So then, brothers and sisters, be eager to prophesy, and do not forbid anyone from speaking in tongues.
