'This Generation' in the Bible

Whereunto therefore shall I compare the men of this generation?

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

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

And the men of Nineveh shall rise up in the judgement against this generation, and condemn it; for they repented upon the preaching of Jonas, and behold a greater than Jonas 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. Verily I tell you, it shall be required of this generation.

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

Verily I tell you, this generation shall not pass away till all be accomplished.
