1The LORD said to Moses, "I will still bring one plague upon Pharaoh and upon Egypt. After this he will let you go from here." When he lets you go, he will surely drive you out from here altogether.2Speak now in the hearing of the people, so that every man may ask his neighbor and every woman her neighbor for vessels of silver and vessels of gold.3The LORD granted the people favor in the sight of the Egyptians. Moreover, the man Moses was very great in the land of Egypt in the sight of Pharaoh's servants and in the sight of the people.4Moses said, "Thus says the LORD: About midnight I will go out into the midst of Egypt."5Every firstborn in the land of Egypt shall die, from the firstborn of Pharaoh who sits on his throne to the firstborn of the maidservant who is behind the millstone, and every firstborn among the animals.6There will be a great cry throughout all the land of Egypt, such as has never been before and such as will never be again.7But against any of the sons of Israel, not even a dog shall move its tongue, whether against man or beast, so that you may know that the LORD makes a distinction between Egypt and Israel.8All these your servants will come down to me and bow down to me, saying, 'Go out, you and all the people who follow you,' and after that I will go out." And he went out from Pharaoh in hot anger."9The LORD said to Moses, "Pharaoh will not listen to you, in order that my wonders may be multiplied in the land of Egypt."10Moses and Aaron performed all these wonders before Pharaoh, yet the LORD hardened Pharaoh's heart, and he did not let the sons of Israel go out of his land.
