'Generation' in the Bible

And the captain of the unsexed servants said to Daniel, I am in fear of my lord the king, who has given orders about your food and your drink; what if he sees you looking less happy than the other young men of your generation? then you would have put my head in danger from the king.

How great are his signs! and how full of power are his wonders! his kingdom is an eternal kingdom and his rule goes on from generation to generation.

And at the end of the days, I, Nebuchadnezzar, lifting up my eyes to heaven, got back my reason, and, blessing the Most High, I gave praise and honour to him who is living for ever, whose rule is an eternal rule and whose kingdom goes on from generation to generation.
