Exodus 11:1-7

Now the LORD said to Moses, “One more plague I will bring on Pharaoh and on Egypt; after that he will let you go from here. When he lets you go, he will surely drive you out from here completely. Speak now in the hearing of the people that each man ask from his neighbor and each woman from her neighbor for articles of silver and articles of gold.” The LORD gave the people favor in the sight of the Egyptians. Furthermore, the man Moses himself was greatly esteemed in the land of Egypt, both in the sight of Pharaoh’s servants and in the sight of the people. Moses said, “Thus says the LORD, ‘About midnight I am going out into the midst of Egypt, and all the firstborn in the land of Egypt shall die, from the firstborn of the Pharaoh who sits on his throne, even to the firstborn of the slave girl who is behind the millstones; all the firstborn of the cattle as well. Moreover, there shall be a great cry in all the land of Egypt, such as there has not been before and such as shall never be again. But against any of the sons of Israel a dog will not even bark, whether against man or beast, that you may understand how the LORD makes a distinction between Egypt and Israel.’
