Proverbs 21:20 - Joseph Benson’s Commentary on the Old and New Testaments

There is a treasure, &c., in the dwelling of the wise Wise men lay up all necessary and desirable treasures for their own use and for their families. Oil is particularly mentioned, because it was a considerable part of their wealth and treasures in those countries; but a foolish man spendeth it Or, as Houbigant renders the clause, A foolish man will dissipate these; or, as Schultens reads it, A foolish man, a man given to luxury and extravagance, absorbs it; “that is, all that desirable treasure and opulence which his wise and careful father had abundantly laid up.”
