'Profit' in the Bible

just as I also please all men in all things, not seeking my own profit but the profit of the many, so that they may be saved.

But now, brethren, if I come to you speaking in tongues, what will I profit you unless I speak to you either by way of revelation or of knowledge or of prophecy or of teaching?

If from human motives I fought with wild beasts at Ephesus, what does it profit me? If the dead are not raised, let us eat and drink, for tomorrow we die.
