'Bold' in the Bible

Then Paul and Barnabas waxed bold, and said, It was necessary that the word of God should first have been spoken to you: but seeing ye put it from you, and judge yourselves unworthy of everlasting life, lo, we turn to the Gentiles.

For [your majesty] the king understands these things, and [therefore] I am also speaking to him with confidence and boldness, since I am convinced that none of these things escape his notice; for this has not been done in a corner [hidden from view, in secret].
