'Foolishly' in the Bible

That which I speak, I speak it not after the Lord, but as it were foolishly, in this confidence of boasting.

I speak as concerning reproach, as though we had been weak. Howbeit whereinsoever any is bold, (I speak foolishly,) I am bold also.

Are they servants of Christ? (I am talking foolishly) I am more so; I have had more experience of hard work, of prisons, of blows more than measure, of death.
