11 There is a generation that curses their father,
and doesn’t bless their mother. 12 There is a generation that is pure in their own eyes,
yet are not washed from their filthiness. 13 There is a generation, oh how lofty are their eyes!
Their eyelids are lifted up. 14 There is a generation whose teeth are like swords,
and their jaws like knives,
to devour the poor from the earth, and the needy from among men.

Matthew Henry's Commentary on Proverbs 30:11-14

Commentary on Proverbs 30:7-14

(Read Proverbs 30:7-14)

In every age there are monsters of ingratitude who ill-treat their parents. Many persuade themselves they are holy persons, whose hearts are full of sin, and who practise secret wickedness. There are others whose lofty pride is manifest. There have also been cruel monsters in every age.
