Exodus 12:29  “And it came to pass at midnight that the LORD struck all the firstborn in the land of Egypt, from the firstborn of Pharaoh who sat on his throne to the firstborn of the captive who was in the dungeon, and all the firstborn of livestock.”
Plague Ten.  Death of the firstborn to everyone and every beast that wasn’t in a house protected by the blood of the Passover lamb.

30  “…there was a great cry in Egypt…”
I would think so.  The cost of not listening to God had finally gotten bad enough to get their attention.  So sad.

31  “…he called for Moses and Aaron by night…”
I’m assuming sent messengers to them.  I don’t think they would have returned to the palace after saying they would not.

32  “…be gone; and bless me also”
No restrictions or exceptions.  Just go as God has told you.  And say a prayer for me while you’re at it.  He’s totally broken for the moment.

33  “…We shall all be dead”
Fear that more would die besides the firstborns.

36  “…Thus they plundered the Egyptians”
Word came while it was still night apparently.  But they were ready to go, so they went.  And they took the wealth of Egypt with them as well.

37  “…six hundred thousand men on foot…”
This many men with likely as many women plus children.  The estimate of two million people isn’t impossible.

38  “A mixed multitude went up with them also…”
Not sure what this refers to exactly.  Commentaries vary.  It apparently says a great rabble, so some think it means some of lower society.  Most think it refers to any who weren’t counted as full Israelites, Egyptians who believed, those who were possibly intermarried with Hebrews, slaves and captives of other nations.  Obviously others who were not Hebrews.

41  “And it came to pass at the end of the four hundred and thirty years—on that very same day—it came to pass that all the armies of the LORD went out from the land of Egypt.”
They had been in Egypt for over four hundred years.  God had used the time to build a nation and to give the other nations in Canaan time to repent, which they didn’t do.

46  “…you shall not carry any of the flesh outside the house, nor shall you break one of its bones”
Everything is to be done in the house.  Can bring in neighbors to keep the ordinance, but don’t take anything outside.  And don’t break any bones of the lamb.  Big point of Christ on the cross, no bones were broken.

48  “…no uncircumcised person shall eat it”
You had to become as a Jew.  Bought servants could partake if they were circumcised and any who chose to be circumcised.  But just being in Israel wasn’t enough.  However, once you were circumcised, you were counted as a Jew.  One law for all.

51  “…according to their armies”
Throws some people off.  Armies is a reference to the masses of people, not necessarily military groups.  Later we’ll read of them moving by tribe.  If the people needed to fight, every able-bodied man would.  But the people moved as a unit, one big army with its fighting and support capabilities all there.  Unfortunately, this has led to some unbelievers to deny the Bible’s account of the Exodus and say it was only a small group of people who led a military rebellion against Egypt.  Don’t know and don’t want to know.

I hope you enjoy reading and studying His word.  May it accomplish what He desires.  Please feel free to comment or post questions.  Thanks for reading!
