'Generation' in the Bible

There is a generation that curse their father, And bless not their mother.

There is a generation that are pure in their own eyes, And yet are not washed from their filthiness.

There is a generation, oh how lofty are their eyes! And their eyelids are lifted up.

There is a generation whose teeth are as'swords, and their jaw teeth as knives, To devour the poor from off the earth, and the needy from among men.
