שהזהיר המוסת מלאהוב המסית ולהאזין לדבריו. והוא אמרו יתעלה לא תאבה לו. ולשון ספרי מכלל שנאמר ואהבת לרעך כמוך יכול אתה אוהב לזה, תלמוד לומר לא תאבה לו. (שם, שם):
That He prohibited an incited one from loving the inciter and from listening to his words. And that is His, may He be exalted, saying, "Do not esteem him" (Deuteronomy 13:9). And the language of the Sifrei (Sifrei Devarim 89:1) is, "It is implied from its being stated, 'you shall love your neighbor like yourself' (Leviticus 19:18) [that] perhaps you should love this one. [Hence] we learn to say, 'Do not esteem him.'" (See Parashat Re'eh; Mishneh Torah, Foreign Worship and Customs of the Nations 5.)
