'This Generation' in the Bible

And the Lord said, To what then shall I compare the men of this generation? and to what are they like?

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

The queen of the south shall rise up in the judgment against the men of this generation, and shall condemn them: for she came from the ends of the earth to hear the wisdom of Solomon, and, behold, a greater than Solomon is here.

The men of Nineveh shall rise up in judgment against this generation, and shall condemn it, for they repented on the preaching of Jonah, and, behold, a greater than Jonah is here.

that the blood of all the prophets, which hath been shed since the foundation of the world, may be required of this generation:

from the blood of Abel to the blood of Zachariah, who was slain between the altar and the temple: verily I tell you, It shall be required of this generation.

But he must first suffer many things, and be rejected by this generation.

Verily I say unto you, That this generation shall in nowise pass away, until all these things come to pass.
