The Bible teaches also that honesty really is the best policy in business dealings. Getting riches by lying will not last:
"Getting treasures by a lying tongue is the fleeting fantasy of those who seek death. The violence of the wicked will destroy them, because they refuse to do justice.''
(Proverbs 21:6-7).
Treasures gotten by wickedness will not profit and God HATES diverse weights use in trade:
"Treasures of wickedness profit nothing, but righteousness delivers from death." (Proverbs 10:2)
"Diverse weights are an abomination to the LORD, and dishonest scales are not good." (Proverbs 20:23).
