'Bad' in the Bible

But Absalom said nothing to his brother Amnon, good or bad: for he was full of hate for him, because he had taken his sister Tamar by force.

Then your servant said, May the word of my lord the king give me peace! for my lord the king is as the angel of God in his hearing of good and bad: and may the Lord your God be with you!

I am now eighty years old: good and bad are the same to me; have meat and drink any taste for me now? am I able to take pleasure in the voices of men or women in song? why then am I to be a trouble to my lord the king?
