11 There is a generation who put a curse on their father, and do not give a blessing to their mother. 12 There is a generation who seem to themselves to be free from sin, but are not washed from their unclean ways. 13 There is a generation, O how full of pride are their eyes! O how their brows are lifted up! 14 There is a generation whose teeth are like swords, their strong teeth like knives, for the destruction of the poor from the earth, and of those who are in need 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.
