'Generation' in the Bible

But what comparison may I make of this generation? It is like children seated in the market-places, crying out to one another,

But he, answering, said to them, An evil and false generation is looking for a sign; and no sign will be given to it but the sign of the prophet Jonah:

The men of Nineveh will come up in the day of judging and give their decision against this generation: because they were turned from their sins at the preaching of Jonah; and now a greater than Jonah is here.

The queen of the South will come up in the day of judging and give her decision against this generation: for she came from the ends of the earth to give ear to the wisdom of Solomon; and now a greater than Solomon is here.

Then he goes and takes with him seven other spirits worse than himself, and they go in and make it their living-place: and the last condition of that man is worse than the first. Even so will it be with this evil generation.

An evil and false generation is searching after a sign; and no sign will be given to it but the sign of Jonah. And he went away from them.

And Jesus, answering, said, O false and foolish generation, how long will I be with you? how long will I put up with you? let him come here to me.

Truly I say to you, All these things will come on this generation

Truly I say to you, This generation will not come to an end till all these things are complete.
