DEUT1466 There are various rulings on non-Jews in the Talmud, including some that are discriminatory. However, even among the most hostile rabbinic figures, we find certain standards of behavior that are binding upon all Jews: It is always forbidden to steal from or deceive anyone, even an idolater (Bava Kamma 113b, Chullin 94a). [A Jew who acts dishonestly is regarded as "abhorrent to the Lord your God" [this verse]. For example, a merchant who knows of a flaw in his merchandise must inform the would-be purchaser--Jew or non-Jew--of it (see Maimonides, "Laws of Sales" 18:1). Indeed, the Rabbis teach that "stealing from a non-Jew is worse than stealing from a Jew because of the profanation of God's name" (Tosefta Bava Kamma 10:15). When a Jew is found to have acted dishonestly toward another Jew, he brings contempt upon himself. But when a Jew acts dishonestly toward a non-Jew, he runs the risk of causing others to view Jews and Judaism with contempt; this makes such behavior even more reprehensible.
