'Boldness' in the Bible

Now when the Jewish leaders saw the boldness of Peter and John and found out that they were uneducated and ordinary men, they were amazed and realized that they had been with Jesus.

in whom we have boldness and confident access through his faithfulness.

I rejoice because I eagerly expect and hope that I will have nothing to be ashamed of, because through my boldness the Messiah will be exalted through me, now as always, whether I live or die.
