'Class' in the Bible

He who robs his father or his motherAnd says, “This is no sin,”Is [not only a thief but also] the companion of a man who destroys.

There is a generation (class of people) that curses its fatherAnd does not bless its mother.

There is a generation (class of people) that is pure in its own eyes,Yet is not washed from its filthiness.

There is a generation (class of people)—oh, how lofty are their eyes!And their eyelids are raised in arrogance.

There is a generation (class of people) whose teeth are like swordsAnd whose jaw teeth are like knives,To devour the afflicted from the earthAnd the needy from among men.
