Exodus 11:4–7

4 So Moses said, “Thus says the Lord: w‘About midnight I will go out in the midst of Egypt, 5 and every firstborn in the land of Egypt shall die, from the firstborn of Pharaoh who sits on his throne, even to the firstborn of the slave girl who is xbehind the handmill, and all the firstborn of the cattle. 6 yThere shall be a great cry throughout all the land of Egypt, such as there has never been, nor ever will be again. 7 But not a dog shall growl zagainst any of the people of Israel, either man or beast, that you may know that the Lord amakes a distinction between Egypt and Israel.’
