To my shame I admit that we were too weak for that! Whatever anyone else dares to boast about – I am speaking as a fool – I also dare to boast about.
NIV
To my discredit, I must say, we have shown ourselves too weak [for you to show such tolerance of us and for us to do strong, courageous things like that to you]! But in whatever any person is bold and dares [to boast]--mind you, I am speaking in this foolish (witless) way--I also am bold and dare [to boast].
AMP
I speak as concerning reproach, as though we had been weak. Howbeit whereinsoever any is bold, (I speak foolishly,) I am bold also.
KJV
