'This Generation' in the Bible

Then to whom shall I liken the men of this generation, and to whom are they like?

For as Jonah was a sign to the Ninevites, so shall the Son of man also be a sign to this generation.

The queen of the south will rise in judgment with this generation, and condemn them; because she came from the uttermost parts of the earth, to hear the wisdom of Solomon; and behold, a greater than Solomon is here.

The men of Nineveh will rise in judgment with this generation, and condemn it: because they repented at the preaching of Jonah; and behold a greater than Jonah is here.

In order that the blood of all the prophets poured out from the foundation of the world, may be required from this generation;

from the blood of Abel unto the blood of Zachariah, who perished between the altar and the house; yea, I say unto you, it shall be required of this generation.

But it behooves Him first to suffer many things and to be set at nought by this generation.
