The Lord demands fairness in every business deal; he sets the standard (Proverbs 16:11). Wow! The Bible really has something to say about everything. I am not a business person but we all make transactions. The true challenge in this verse seems to be with who sets the standard. We probably all aim for fairness in our dealings, but often will do something contrary if "everyone is doing it" or "that's how it's done" or "I know it sounds bad, but..." I encourage us all to go above and beyond the "acceptable" thing to live and act according to the Lord's standard.
