One must beware from theft, and conduct trade in good faith, not only with the People of Israel, for one must beware from cheating a non-Jew, which incurs severe punishment and is a great desecration of God's Name. Although one may benefit from a non-Jew's error when they themselves make a mistake - and this involves no desecration of God's Name - misleading a non-Jew as some do, whether by sliding a poor quality and thin coin in lieu of a thick and good one, or by giving poor quality or thin goods instead of good quality and thick goods by switching them while measuring is absolute theft. This is all the result of a lack of faith in God, for it is He who enriches and bequeaths, and they seek to profit from the sin of theft. Although it may, at the time, seem that profit is being made, in any case this will eventually lead to financial downfall, heaven forbid, in addition to the punishment reserved for Judgment Day. Our sages, of blessed memory, said, "Where there is no judgement below there is judgement above". They are to keep in mind that even if they fear no person, they are to fear the Holy One, blessed be He, in the heavens above, who sees and examines people's deeds and, as it were, recompenses people for their ways and for the fruits of their actions. And we are certain that the saintly People of Israel, sons of Abraham, Isaac and Jacob, will no longer do any such deeds, and will beware from desecrating the Sabbath and from the interdiction of theft, even from non-Jews, and that the benediction of goodness will be upon them.
