Mikraot Gedolot — Genesis 32:9
“ Ramban one camp and struck it down הַמַּחֲנֶ֥ה הָאַחַ֖ת וְהִכָּ֑הוּ On the literal level he said that this as a possibility. That he said one camp might exploit that hit each other escape, or his [Esau’s] anger might rest, or rescue might come from God. And said in Genesis Rabbah (Genesis Rabbah 76:3) : "The Torah teaches the proper way, that a man should not lay down all of his money in one corner." Rashi wrote: "The other camp would survive, against his will, because I [Jacob] , will fight with him." ”
