Sha'arei Kedusha
Fraud has two great evils. The first is that it is similar to the matter of falsehood and hypocrisy, and the second is that it is like theft and deception. In doing so, he denigrates the Name of HaShem-יהו״ה, blessed is He, and thinks to himself that the Holy One, blessed is He, does not see his deception, God forbid. It is written,629Leviticus 25:17 “Each of you shall not defraud his fellow, and you shall fear your God, for I am HaShem-יהו״ה your God,” and it is written,630Leviticus 19:35 “You shall not commit a perversion of justice, in measures of length, weight, or volume. You shall have correct scales, correct weights, correct dry measures, and correct liquid measures – I am HaShem-יהו״ה your God.” At the beginning of one’s judgement after passing from this world, he is asked, “Did you conduct your business faithfully?”631Talmud Bavli, Shabbat 31a – That is, with honesty and integrity.
