'Generation' in the Bible

The book of the generation of Jesus Christ, the son of David, the son of Abraham.

But when he saw many of the Pharisees and Sadducees come to his baptism, he said unto them, O generation of vipers, who hath warned you to flee from the wrath to come?

But whereunto shall I liken this generation? It is like unto children sitting in the markets, and calling unto their fellows,

O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh.

But he answered and said unto them, An evil and adulterous generation seeketh after a sign; and there shall no sign be given to it, but the sign of the prophet Jonas:

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

The queen of the south shall rise up in the judgment with this generation, and shall condemn it: for she came from the uttermost parts of the earth to hear the wisdom of Solomon; and, behold, a greater than Solomon is here.

Then goeth he, and taketh with himself seven other spirits more wicked than himself, and they enter in and dwell there: and the last state of that man is worse than the first. Even so shall it be also unto this wicked generation.

A wicked and adulterous generation seeketh after a sign; and there shall no sign be given unto it, but the sign of the prophet Jonas. And he left them, and departed.

Then Jesus answered and said, O faithless and perverse generation, how long shall I be with you? how long shall I suffer you? bring him hither to me.

Ye serpents, ye generation of vipers, how can ye escape the damnation of hell?

Verily I say unto you, All these things shall come upon this generation.

Verily I say unto you, This generation shall not pass, till all these things be fulfilled.
