'This Generation' in the Bible

And the Lord said, "Whereunto shall I liken the men of this generation: and what thing are they like?

The queen of the south shall rise at the judgment, with the men of this generation, and condemn them. For she came from the end of the world, to hear the wisdom of Solomon: and behold a greater than Solomon is here.

The men of Nineveh shall rise at the judgment, with this generation, and shall condemn them: for they repented at the preaching of Jonah: And behold, a greater than Jonah is here.

That the blood of all prophets, which was shed from the beginning of the world, may be required of this generation,

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