'This Generation' in the Bible

But to what shall I liken this generation? It is like to children sitting in the markets, and calling to their fellows,

The men of Nineveh shall rise in judgment with this generation, and shall condemn it: because they repented at the preaching of Jonah; and behold, a greater than Jonah is here.

The queen of the south shall rise up in the judgment with this generation, and shall condemn it: for she came from the uttermost parts of the earth to hear the wisdom of Solomon; and behold, a greater than Solomon is here.

Verily I say to you, all these things shall come upon this generation.

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