"For not as our rock is their rock": Not as the authority you give us is the authority you give them. When you give authority to them, they treat us with cruelty: they kill us, burn us, and crucify us.
"and our foes are judges": You wrote in our Torah that a foe does not judge and does not testify, viz. (Bamidbar 35:23) "And one who is not his foe" (shall testify against him), "and one who does not seek his evil" (shall judge him). And You have placed over us foes as witnesses and judges!
(Devarim, Ibid. 32) "For of the wine of Sodom is their wine": R. Yehudah expounds this as referring to Israel; and R. Nechemiah, as referring to the nations.
