The fourth, The greedy, cruel, and oppressive, and, especially, oppressive to the poor.
Matthew Henry
Concise Bible Commentary
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.
