'This Generation' in the Bible

"But to what shall I liken this generation? It is like children sitting in the marketplaces, who, calling to the others,

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

"A queen of the south will rise up in the judgment with this generation, and will condemn it; because she came from the ends 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 will not pass away, until all these things come to pass.
