Arso, so did you clarify yet with a talmid chuchem if “Yacov lo mes” means that Yacov’s guf is physically alive? Because as I’ve said, I have never heard a rav or talmid chuchem say that it means that his guf is alive and ive listened to many of them speaking on the subject. I’ve only heard it from Lubavitche and you. Don’t calk me an apikorus when I’m saying what I heard from talmidei chachumim. Perhaps you are the apikorus. You should clear that up with a reputable, non-Chabad, rabbi.
As I’ve said, if you have a Rabbi or talmud chuchem saying that Yacov lo mes means that Yacov’s guf is alive n his kever then post the rabbi’s name on this thread or the other one. (Still) Awaiting your response.
