'Generation' in the Bible

What comparison am I to make of the men of this generation? what are they like?

And Jesus said, O generation without faith and false in heart, how long will I have to be with you and put up with you? let your son come here.

And when a great number of people came together to him, he said, This generation is an evil generation: it is looking for a sign and no sign will be given to it but the sign of Jonah.

For even as Jonah became a sign to the Ninevites, so will the Son of man be to this generation.

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

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

So that punishment may come on this generation for the blood of all the prophets which was given from the earliest days;

From the blood of Abel to the blood of Zachariah, who was put to death between the altar and the Temple. Yes, I say to you, It will come on this generation.

And his lord was pleased with the false servant, because he had been wise; for the sons of this world are wiser in relation to their generation than the sons of light.

But first, he will have to undergo much and be put on one side by this generation.

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