לא תדרוש שלומם וטובתם. מכלל שנ' וקראת אליה לשלום, יכול אף אלו כן? ת"ל לא תדרוש שלומם.
(Devarim 23:7) "Do not seek their peace and their good all of your days, forever": Because it is written (Ibid. 20:10) "and you shall call out to it (a besieged city) for peace," I might think that the same should be done with them (Amon and Moav); it is, therefore, written "Do not seek their peace."
