'Generation' in the Bible

But he replied to them, "An evil and adulterous generation craves a sign. Yet no sign will be given to it except the sign of the prophet Jonah,

Then it goes and brings with it seven other spirits more evil than itself, and they go in and settle there. And so the final condition of that person becomes worse than the first. That's just what will happen to this evil generation!"

You know how to interpret the appearance of the sky, yet you can't interpret the signs of the times? An evil and adulterous generation craves a sign, but no sign will be given to it except the sign of Jonah." Then he left them and went away.

Jesus replied, "You unbelieving and perverted generation! How long must I be with you? How long must I put up with you? Bring him here to me!"

I tell all of you with certainty, this generation won't disappear until these things happen.
