신명기 32:31의 Halakhah

"Before them," but not before gentiles: Even if with regard to a particular suit you know that they rule in a manner consistent with the laws of Israel, do not bring it before their courts, for one who brings Jewish lawsuits before gentiles profanes the Name of God and ascribes honor to the name of the idols, thereby enhancing their stature (le-haḥashivam),¹²A variant version reads “le-hashbiḥam” which, in this context, must be understood as having the same connotation. as it is said, "For their rock is not our Rock, nor our enemies judges" (Deuteronomy 32:31), i.e., [if we make] our enemies judges [over us] that is testimony to the superiority of that which they reverence.¹³See also the supercommentary of R. Eliyahu Mizraḥi, ad locum.
