'Bold' in the Bible

And [if my head] grows bold, you would hunt me as the lion in its prime; {and you repeat your exploits against me}.

And empty man is bold, And the colt of a wild ass man is born.

“Is there no end to [your futile] words of wind?Or what plagues you [so much] that you [so boldly] answer [me like this]?

None is so bold as to stir him up; and who is he that will stand before me?
