'Generation' in the Bible

Tell ye your children of it, and let your children tell their children, and their children another generation.

A day of doom and gloom, a day of clouds and shadows like the dawn spreads out to cover the mountains a people strong and robust. Never has there been anything like it, neither will anything follow to compare with it, even through the lifetime of generation upon generation."

But Judah shall dwell for ever, and Jerusalem from generation to generation.
