WIY,, yes, I did consider that. I wonder if the Nazis would have done the same.
My former Rov spoke about the breaking bread (literally) issue. Paroh would never eat with Yosef, because he knew him to be a Hebrew. Lamb was not served in the palace, being that it was their god. So the idea that lamb would have been eaten by the brothers makes no sense to me. Paroh would not have allowed the lambs to be slaughtered, cooked, and eaten by “vermin” like Hebrews. That’s what made the putting of lamb’s blood on the mezuzos of the Jewish doorways such a defiant act, in yetzias Mitzrayim. Jews were slaughtering their god, and they were helpless to stop it.
