'Take Pleasure In' in the Bible

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?

And Joab said to the king, Whatever the number of the people, may the Lord make it a hundred times as much, and may the eyes of my lord the king see it: but why does my lord the king take pleasure in doing this thing?
