Tikva Chukot Ákum

MISHNA: And these are the festivals of gentiles: Kalenda, Saturnalia, and Kratesis, and the day of the festival of their kings, and the birthday of the king, and the anniversary of the day of the death of the king. This is the statement of Rabbi Meir. And the Rabbis say: Every death that includes public burning is a festival that includes idol worship, and any death that does not include public burning is not a festival that includes idol worship. But in the case of the day of shaving his, i.e., a gentile’s, beard and his locks, and the day of his ascent from the sea, and the day that he left prison, and also in the case of a gentile who prepared a wedding feast for his son and celebrates on that day, engaging in business is prohibited only on that day and with that man.

1. Not To Dress Like A Non-Jew, 3 Seifim: One [i.e., a Jew] should not follow the customs of non-Jews (nor should one try to resemble them) (Tur in the name of the Rambam). One should not wear clothing that is particular to them [i.e., their culture]; one should not grow forelocks on one’s head like the forelocks on their heads; one should not shave the sides [of one’s head] and grow one’s hair in the middle of one’s head [like they do]; one should not shave the hair in front of one’s face from ear to ear and let one’s hair grow [in the back] [like they do]; one should not build places [i.e., buildings]—like the non-Jews’ temples—so that large groups of people will enter them, like [non-Jews] do. RAMA: Rather, one [i.e., a Jew] should be distinct from them [i.e., non-Jews] in one’s manner of dress and in all of one’s actions. But all of this [i.e., these restrictions] apply only to things that non-Jews do for the sake of licentiousness. For example, they are accustomed to wearing red clothing, which is official/princely clothing, and other clothing that is similarly immodest. [These restrictions also apply] to things that they are accustomed to doing because of a custom or rule that does not have a[ny underlying] reason, out of concern that [a Jew who does such things will follow the] “ways of the Amorites,” and that it has the blemish of [i.e., is tainted by] idol worship inherited from their ancestors. But things that they are accustomed to doing for a useful purpose—such as their custom for expert doctors to wear particular clothing so that the doctors will be recognized as specialists—one is permitted to wear [such clothing]. (Maharik Shoresh 88) Similarly, things that are done out of respect or another reason, it is permitted [for one to do such things]. And therefore they said one may burn [the items of deceased] kings, and there is not in this “the ways of the Amorites.” (R"an, Chapter of the Laws of Non-Jews) 2. One [i.e., a Jew] who is close [i.e., works closely] with the [non-Jewish] authorities and is required to dress in their clothing and to be similar [in appearance] to them, is permitted in all respects [to do so]. 3. One who eats and on his table, does not bring a full loaf and place it on the table. RAMA: There are places to set the table and place upon it some (types) of food at night for the next day...
