11 There are those who curse their fathers and do not bless their mothers. 12 There are those who are pure in their own eyes yet are not cleansed of their filthiness. 13 There are those-how lofty are their eyes, how high their eyelids lift!- 14 there are those whose teeth are swords, whose teeth are knives, to devour the poor from off the earth, the needy from among mortals.
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.
