Exodus 11:4-7

4So Moses said, “Thus says the Lord: a‘About midnight I will go out in the midst of Egypt, 5and 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 bbehind the handmill, and all the firstborn of the cattle. 6 cThere shall be a great cry throughout all the land of Egypt, such as there has never been, nor ever will be again. 7But not a dog shall growl dagainst any of the people of Israel, either man or beast, that you may know that the Lord emakes a distinction between Egypt and Israel.’
