Allah (Hashem) Himself Will Carry Out this Plague

The Tenth Plague: Death of the First Born

I shall go through the land of Egypt on this night and I shall strike every first born in the land of Egypt, from man to beast and against the god’s of Egypt I shall mete out punishment-I am Allah (Hashem). The blood (lamb) shall be a sign for you upon the houses where you are; I shall see the blood and shall pass over you; there shall be a plague of destruction upon you when I strike in the land of Egypt.

This day will come as a remembrance of you and you shall celebrate it as a festival for Allah (Hashem); for your generation, as an eternal decree shall you celebrate it. For a seven-day period shall you eat matzos [Unleavened, without yeast (sin)], until the twenty-first day of the month in the evening.

Moses called to the elders among his people and said to them, “Draw forth or buy for yourselves one of the flocks for your families and slaughter the pesach-offering. You shall take a bundle of hyssop and dip it into the blood (lamb) that is in the basin and touch the lintel and the two doorposts with some of the blood that is in the basin and as for you, no man shall leave the entrance of the house until morning. Allah (Hashem) will pass through to smite Egypt and He will see the blood that is on the lintel and the two doorposts; and Allah (Hashem) will pass over the entrance and will not admit the destroyer to enter your house to smite. You shall observe this matter as a decree (and a remembrance of observance) for yourself and your children forever.

It was at midnight that Allah (Hashem) smote every firstborn in the land of Egypt, from the firstborn of Pharaoh sitting upon his throne to the firstborn of the captive that was in his dungeon (freedom from suffering), and every firstborn animal. Pharaoh rose up at midnight, he and all his servants and all Egypt, and there was a great outcry in Egypt, for there was not a house where there was no corpse. He called to Moses and Aaron at night and said, “Rise up, go out from among my people, even you, even the children of your people; go and serve Allah (Hashem) as you have spoken! Take even your sheep and even your cattle, as you have spoken and go-and bless me as well!”

Exodus/Shemos

The people picked up its dough before it could become leavened, their leftovers bound up their garments upon their shoulders. Those blessed by Allah (Hashem) carried out the word of Moses; they requested from the Egyptians silver vessels, gold vessels and garments. Allah (Hashem) gave favor in the eyes of the Egyptians and they granted their request-so they where allowed to empty Egypt.

All those blessed by Allah (Hashem) (every man, woman, child and elderly; about three million souls) journeyed from Rameses to Succoth, about six hundred thousand (adult males) men on foot, aside from the children. Also a mixed multitude went up with them (from Ethiopia to Syria) and flock and cattle, a variety of very much livestock.
For the habitation in Egypt of the children blessed by Allah (Hashem) was four hundred and thirty years and in all this time, hope and faith was never swayed from Allah (Hashem) nor did He stop listening to their cries and sufferings; even with the thought of their journey into the wilderness, to even the event that led up to the fourty-year exile in the wilderness.

What is often not mentioned is when Prophet Moses freed the Jewish slaves; he also freed all slaves that had been captured from the many places in the known world. When Prophet Moses headed across the desert towards Israel, the other people headed towards there respective homes. -HRM Deborah
