Proverbs 30:12-14

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 swords And whose jaw teeth are like knives, To devour the afflicted from the earth And the needy from among men.
