'This Generation' in the Bible

You people of this generation, listen to what the Lord says. "Have I been like a wilderness to you, Israel? Have I been like a dark and dangerous land to you? Why then do you say, 'We are free to wander. We will not come to you any more?'

So, mourn, you people of this nation. Cut off your hair and throw it away. Sing a song of mourning on the hilltops. For the Lord has decided to reject and forsake this generation that has provoked his wrath!'"
