'Speaks' in the Bible

Is God simply thinking about the oxen? Or is it really in our interest that He speaks? Of course, it was written in our interest, because it is His will that when a plough-man ploughs, and a thresher threshes, it should be in the hope of sharing that which comes as the result.

For the person who speaks in another language is not speaking to men but to God, since no one understands him; however, he speaks mysteries in the Spirit.

But the person who prophesies speaks to people for edification, encouragement, and consolation.

The person who speaks in another language builds himself up, but he who prophesies builds up the church.

I wish all of you spoke in other languages, but even more that you prophesied. The person who prophesies is greater than the person who speaks in languages, unless he interprets so that the church may be built up.

If therefore I do not know the power of the sound, I shall be to him that speaks a barbarian, and he that speaks a barbarian for me.

Therefore the person who speaks in another language should pray that he can interpret.

If any person speaks in another language, there should be only two, or at the most three, each in turn, and someone must interpret.
