Adam Clarke on Proverbs 13:22

A good man leaveth an inheritance - He files many a prayer in heaven in their behalf, and his good example and advices are remembered and quoted from generation to generation. Besides, whatever property he left was honestly acquired, and well-gotten goods are permanent. The general experience of men shows this to be a common case; and that property ill-gotten seldom reaches to the third generation. This even the heathens observed. Hence:

De male quaesitis non gaudet tertius haeres. "The third generation shall not possess the goods that have been unjustly acquired."
