Adam Clarke on Proverbs 28:8

He that by usury - increaseth his substance - By taking unlawful interest for his money; lending to a man in great distress, money, for the use of which he requires an exorbitant sum. O that the names of all those unfeeling, hard-hearted, consummate villains in the nation, who thus take advantage of their neighbour's necessities to enrich themselves, were published at every market cross; and then the delinquents all sent to their brother savages in New Zealand. It would be a happy riddance to the country.
