'Bold' in the Bible

Now I Paul, myself, entreat you by the humility and gentleness of Christ; I who in your presence am lowly among you, but being absent am bold toward you.

Yes, I beg you that I may not, when present, show courage with the confidence with which I intend to be bold against some, who consider us to be walking according to the flesh.

For we are not bold to number or compare ourselves with some of those who commend themselves. But they themselves, measuring themselves by themselves, and comparing themselves with themselves, are without understanding.

I speak by way of disparagement, as though we had been weak. Yet however any is bold (I speak in foolishness), I am bold also.
