'This Generation' in the Bible

"To what then shall I compare the men of this generation?

"for as Jonah became a sign to the Ninevites, so shall the Son of man be to this generation.

"The queen of the South shall rise up in Judgment with the men of this generation, and shall condemn them; because she came from the ends of the earth to listen to the wisdom of Solomon, and lo, one greater than Solomon is here!

"so that the blood of all the prophets which was shed from the foundation of the world may be required from this generation,

"from the blood of Abel to the blood of Zachariah, who perished between the alter and the sanctuary; yes; I tell you, it shall be required of this generation!

"In solemn truth I tell you that this generation shall not pass away until all this happens.
