What is the meaning of "Hago Sigim mi'Kasef"?
1.
Rashi: "Hago" is distanced, like "Hogah Min ha'Mesilah" (Shmuel II, 20:13). Just like a silver Kli does not go to the smelter's work, until they remove from it the copper dross in it, so the Tzibur is not exempted from punishment until Resha'im are removed from them, and they are judged.
