“Now learn this lesson from the fig tree: As soon as its twigs get tender and its leaves come out, you know that summer is near. Even so, when you see all these things, you know that it is near, right at the door. I tell you the truth, this generation will certainly not pass away until all these things have happened. Matthew 24:32-34

“To what can I compare this generation? They are like children sitting in the marketplaces and calling out to others.” Matthew 11:16

Those standing in front of him will live to see Him judge this Jewish kingdom and the beginning of a new kingdom (without the temple).
