Not to take out from the meat of the Pesach-offering outside
“From the roots of this commandment is that which we have written — to remember the miracles of Egypt. And since we were made into free men and lords, this commandment came to us that we should eat [it] in the place of the assemblage and not take it outside — like the kings of the land.”
