LEV805 Let the ethics and decency of Torah not stop at the doors of the beth midrash, the House of Study. Conduct your business in the spirit of the Torah. Remain honest, honorable, fair. The Torah commands, "You shall do no wrong in judgment, in measures of length, weight, quantity" [this verse] Rabbi Isaac Scher, the head of the Slobodka Yeshiva, quoted Midrash Sifra that "judgment," which usually refers to the judicial process in a court of law, is used here about the business of weights and measures mentioned after it. The Torah speaks to a merchant who is measuring a yard of material: At this moment you are a judge and your action is tantamount to a legal decision. This is a case involving you and the customer. A certain amount of merchandise goes to your customer; the balance remains for you; and a sum of money changes hands. Give him thirty-five inches instead of the full yard, and you have robbed him. Charge him less than the fair price and you are cheating yourself.
