Exodus 11:1-10 - The Tenth Plague: Death Of The Firstborn
1 And the LORD said unto Moses, "Yet will I bring one plague more upon Pharaoh and upon Egypt, and after that he will let you go hence. And when he letteth you go, he shall utterly drive you hence. 2 But bid the people that every man borrow of his neighbor and every woman of her neighboress: jewels of silver and jewels of gold." 3 And the LORD gat the people favour in the sight of the Egyptians. Moreover, Moses was very great in the land of Egypt: both in the sight of Pharaoh, and also in the sight of the people.
4 And Moses said, "Thus sayeth the LORD, 'About midnight will I go out among the Egyptians, 5 and all the firstborn in the land of Egypt shall die: even from the firstborn of Pharaoh that sitteth on his seat, unto the firstborn of the maidservant that is in the mill, and all the firstborn of the cattle. 6 And there shall be a great cry throughout all the land of Egypt: so that there was never none like, nor shall be. 7 And among all the children of Israel shall not a dog move his tongue, nor yet man or beast: that ye may know, how the LORD putteth a difference between the Egyptians and Israel.' 8 And all these thy servants shall come down unto me, and fall before me and say, 'Get thee out and all the people that are under thee!' And then will I depart." And he went out from Pharaoh in a great anger.
9 And the LORD said unto Moses, "Pharaoh shall not regard you, that many wonders may be wrought in the land of Egypt." 10 And Moses and Aaron did all these wonders before Pharaoh. But the LORD hardened Pharaoh's heart, so that he would not let the children of Israel go out of his land.
