'This Generation' in the Bible

“To what then shall I compare the people of this generation [who set aside God’s plan], and what are they like?

The men of Nineveh will stand up [as witnesses] at the judgment with this generation and condemn it, because they repented at the preaching of Jonah, and look, something greater than Jonah is here.

I assure you and most solemnly say to you, this generation [those living at that definite period of time preceding the second coming] will not pass away until everything takes place.
