'Generation' in the Bible

Give the story of it to your children, and let them give it to their children, and their children to another generation.

For a day of dark and deep shade is near, a day of cloud and black night: like a black cloud a great and strong people is covering the mountains; there has never been any like them and will not be after them again, from generation to generation.

But Judah will be peopled for ever, and Jerusalem from generation to generation.
