'This Generation' in the Bible

"To what then will I liken the people of this generation? What are they like?

For even as Jonah became a sign to the Ninevites, so will also the Son of Man be to this generation.

The Queen of the South will rise up in the judgment with the men of this generation, and will condemn them: for she came from the ends of the earth to hear the wisdom of Solomon; and behold, one greater than Solomon is here.

The men of Nineveh will stand up in the judgment with this generation, and will condemn it: for they repented at the preaching of Jonah, and behold, one greater than Jonah is here.

that the blood of all the prophets, which was 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 sanctuary.' Yes, I tell you, it will be required of this generation.

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

Most certainly I tell you, this generation will not pass away until all things are accomplished.
