'This Generation' in the Bible

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

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

The queen of the south shall rise in the judgment with the men of this generation, and shall condemn them; for she came from the most distant parts of the earth to hear the wisdom of Solomon; and lo, something greater than Solomon is here.

The men of Nineveh shall rise in the judgment with this generation, and condemn it; for they repented in accordance with the preaching of Jonah; and lo. something greater than Jonah is here.

that the blood of all the prophets, which has been shed from the foundation of the world, may be required of this generation;

from the blood of Abel to the blood of Zachariah, who perished between the altar and the temple; yes, I say to you, It shall be required of this generation.

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

Verily I say to you, This generation shall not pass away till all be fulfilled.
