'Generation' in the Bible

“To what should I compare this generation? It’s like children sitting in the marketplaces who call out to each other:

But He answered them, “An evil and adulterous generation demands a sign, but no sign will be given to it except the sign of the prophet Jonah.

The men of Nineveh will stand up at the judgment with this generation and condemn it, because they repented at Jonah’s proclamation; and look—something greater than Jonah is here!

The queen of the south will rise up at the judgment with this generation and condemn it, because she came from the ends of the earth to hear the wisdom of Solomon; and look—something greater than Solomon is here!

Then off it goes and brings with it seven other spirits more evil than itself, and they enter and settle down there. As a result, that man’s last condition is worse than the first. That’s how it will also be with this evil generation.”

An evil and adulterous generation demands 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 rebellious generation! How long will I be with you? How long must I put up with you? Bring him here to Me.”

I assure you: All these things will come on this generation!

I assure you: This generation will certainly not pass away until all these things take place.
