Characteristic of Rabbi Nathan’s trend of thoughts are the following social, ethical and religious maxims which he based on the text of the Torah. The verse: “You shall not wrong or oppress a stranger for you were strangers in the land of Egypt” (Ex. 22:20) Rabbi Nathan interpreted that “a man should never accuse others of the fault from which he is suffering”.⁸⁾בבא מציעא נ״ט ב׳, מסכת גרים פרק ד׳.
