'Foolishness' in the Bible

I wish you would put up with a little foolishness from me. Yes, do put up with me.

That which I speak, I speak not according to the Lord, but as in foolishness, in this the confidence of boasting;

in reference to dishonour I speak, how that we were weak, and in whatever any one is bold -- in foolishness I say it -- I also am bold.
