'Fool' in the Bible

I say again, let no one think that I am a fool. But if you do, then at least accept me as a fool, so that I too may boast a little.

For even if I wish to boast, I will not be a fool, for I would be telling the truth, but I refrain from this so that no one may regard me beyond what he sees in me or what he hears from me,

I have become a fool. You yourselves forced me to do it, for I should have been commended by you. For I lack nothing in comparison to those "super-apostles," even though I am nothing.
