Charles Ellicott Commentary Proverbs 20:14

"It is bad, it is bad, saith the buyer; But when he is gone his way, then he boasteth." — Proverbs 20:14 (ASV)

It is naught, saith the buyer.—He disparages the goods he wants to purchase.

Then he boasteth.—He boasts of how he has outsmarted the seller and acquired the goods below their value. For other mentions of cheating in trade, see the commentary above on Proverbs 11:1.
