The Final Plague of Egypt
The Lord (to Moses): I will bring one more plague on Pharaoh and on Egypt. Afterwards he will let you go from here. When he lets you go, he will surely thrust you altogether out from here. Speak now in the ears of the people. Let every man borrow from his neighbor. Let every woman borrow jewels of silver and jewels of gold from her neighbor.
The Lord gave the people favor in the sight of the Egyptians. In addition, Moses was a very great man in the land of Egypt, in the sight of Pharaoh’s servants, and in the sight of the people.
Moses: The Lord said this, About midnight I will go out into the middle of Egypt: And all the firstborn in the land of Egypt shall die, from the firstborn of Pharaoh who sits on his throne, even to the firstborn of the maidservant who is behind the mill; and all the firstborn of beasts. And there shall be a great cry throughout all the land of Egypt, such as there was none like it, nor shall be like it any more. But against the children of Israel shall not a dog move his tongue, against man or beast: that you may know how the Lord puts a difference between the Egyptians and Israel. And all your servants shall come down to me, and bow down themselves to me, saying, Get out, you and all the people that follow you. After that I will go out.
And Moses went out from Pharaoh in a great anger.
The Lord (to Moses): Pharaoh will not listen to you; that my wonders may be multiplied in the land of Egypt.
And Moses and Aaron did all these wonders before Pharaoh: and the Lord hardened Pharaoh’s heart, so that he would not let the children of Israel go out of his land.
Note: You might question that the Lord hardened Pharaoh’s heart. Isn’t that wrong of God?
We are given the answer in Romans 9:14-18.
What shall we say then? Is there unrighteousness with God? God forbid. For God said to Moses, I will have mercy on whom I will have mercy, and I will have compassion on whom I will have compassion. So then it is not of him who wills nor of him who runs, but of God who shows mercy. For the scripture says of Pharaoh, Even for this same purpose have I raised you up, that I might show my power in you, and that my name might be declared throughout all the earth. Therefore God has mercy on whom he will have mercy, and whom he will he hardens.
