Egyptians Burying Their Dead
Numbers 33.3-4, "...Israel went out with boldness in the sight of all the Egyptians.  For the Egyptians
were burying all their firstborn, whom the Lord had killed among them...."  

Some early 14th Passover advocates have asked, "Why would the Egyptians be burying
their dead so soon; does this seem logical?”

First, we must realize that to the Egyptians this was a plague or epidemic that could likely
spread.  It is common practice in a plague to bury the dead as quickly as possible as well
as to burn everything contaminated by the body.  Every house had a dead person (Exodus
12.30) so the Egyptians had to strengthen themselves to stop this epidemic by burying
their dead as quickly as possible.  They had to forego discreet formalities.  It is quite
possible that Pharaoh had ordered them to bury the dead immediately.  They had been
through several plagues by this time and no doubt had become experts at dealing with the
dead bodies of frogs, cattle, and now – human beings.  Another possibility is that they
were only preparing the graves for burying – the phrase “were burying” is active and
ongoing.  Another possibility is that their culture required them to bury their dead within
24 hours.
