'Generation' in the Bible

for wealth is not for ever; and doth the crown endure from generation to generation?

There is a generation that curseth their father, and doth not bless their mother;

there is a generation that are pure in their own eyes, yet are not washed from their filthiness;

there is a generation, how lofty are their eyes, how their eyelids are lifted up!

a generation whose teeth are swords, and their jaw-teeth knives, to devour the afflicted from off the earth, and the needy from among men.
