YW Moderator 42: Yes, that comes from the phrase “??? ???? ????”, the word ???? stands for ?? ????? ?? ?????? whose neshama came to the Jewish people because of what happened between Shechem and Dina. Basically the nitzotzos of kedusha, or whatever we call it, that were stimulated by that happening, brought out some kedusha in the world, and that’s why it had to happen. So that’s how we know that Shechem wasn’t entirely bad.
It’s a bit like Yaakov Avinu not marrying Timna, some say he should have and that would have prevented Amalek.
