Sipi para sa Genesis 32:9

(5) And this is the explanation of the Text above: "if Esav comes onto one of the camps and attacks", meaning, even if he attacks me in one of the camps, that is, thought, that he should confuse me, God forbid, "and the other camp will be left over" it really wants to say that then, in any instance, the other camp, which is speech, will remain for me, and then through speech I will fortify myself and return to my first camp, which is the world of thought. This is "as a remnant פליטה", an expression for a thing that escapes נפלט its swallowing, meaning, through speech one can save לפלוט the first level. And this is the explanation of Rashi z"l: "against his will that I will fight him", meaning, through speech one can fight and strengthen oneself, and return to one's holiness and thoughts as they were in the beginning. And this is the way of behaving of a tzadik. And in any instance, the tzadik always prays that they would not interrupt their holiness and their thoughts being directed to the Higher World. And this is easy to understand.
