EXOD243 On the same page on which the Rabbis record Hillel's statement of Judaism's essence [That which is hateful to you do not do to another; that is the entire Torah, and the rest is its interpretation. Go study.], the Talmud proposes that the first question the Heavenly Court puts to someone who has died is "did you conduct your business affairs honestly?" Shabbat 31a. Another rabbinic source suggests just how significantly the Rabbis regarded business honesty: "One who deals honestly in business, and his fellow men are pleased with him, is considered as if he fulfilled the entire Torah" Mechilta, Beshalach on this verse.
