'This Generation' in the Bible

"But whereunto shall I liken this generation? It is like unto children, which sit in the market, and call unto their fellows,

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

Verily I say unto you, all these things shall light upon this generation.

Verily I say unto you, that this generation shall not pass, till all these be fulfilled.
