They will not fight you all except within fortified cities or from behind walls. Their violence among themselves is severe. You think they are together, but their hearts are diverse. That is because they are a people who do not reason.
Tafseer
{ لا يقاتلونكم } أي اليهود {جميعا} مجتمعين {إلا في قرى محصنة أو من وراء جدار} سور ، وفي قراءة جدر { بأسهم } حربهم { بينهم شديد تحسبهم جميعا } مجتمعين { وقلوبهم شتى } متفرقة خلاف الحسبان { ذلك بأنهم قوم لا يعقلون } .
{They will not fight you} meaning the Jews {all together} together {except in fortified villages or from behind a wall} a wall, and in another reading, walls {their might} their war {among themselves is severe. You would think they are all together} together {but their hearts are divided} scattered, contrary to what you think. {That is because they are a people who do not understand.}
