'Generation' in the Bible

For riches [are] not forever, nor a crown for generation [after] generation.

[There is] a generation [that] will curse its father, and its mother it will not bless.

[There is] a generation [that is] pure in its own eyes, but from its filthiness it will not be cleansed.

[There is] a generation--how lofty [are] their eyes! And their eyelids they will lift.

[There is] a generation whose teeth [are] swords, and its jawbones, knives, [in order] to devour the poor from the earth and the needy from humankind.
