'This Generation' in the Bible

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

And when the multitudes were gathering together unto him, he began to say, This generation is an evil generation: it seeketh after a sign; and there shall no sign be given to it but the sign of Jonah.

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

The queen of the south shall rise up in the judgment with 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 stand up in the judgment with this generation, and shall condemn it: for they repented at the preaching of Jonah; and behold, a 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 unto the blood of Zachariah, who perished between the altar and the sanctuary: yea, I say unto you, it shall be required of this generation.

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

Verily I say unto you, This generation shall not pass away, till all things be accomplished.
