Exodus 11:4–8

So Moses said, “Thus says the Lord: ‘About midnight I will go out in the midst of Egypt, 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 behind the handmill, and all the firstborn of the cattle. There shall be a great cry throughout all the land of Egypt, such as there has never been, nor ever will be again. But not a dog shall growl against any of the people of Israel, either man or beast, that you may know that the Lord makes a distinction between Egypt and Israel.’ And all these your servants shall come down to me and bow down to me, saying, ‘Get 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.

So Moses said, “This is what the Lord says: ‘About midnight I will go throughout Egypt. Every firstborn son in Egypt will die, from the firstborn son of Pharaoh, who sits on the throne, to the firstborn son of the female slave, who is at her hand mill, and all the firstborn of the cattle as well. There will be loud wailing throughout Egypt—worse than there has ever been or ever will be again. But among the Israelites not a dog will bark at any person or animal.’ Then you will know that the Lord makes a distinction between Egypt and Israel. All these officials of yours will come to me, bowing down before me and saying, ‘Go, you and all the people who follow you!’ After that I will leave.” Then Moses, hot with anger, left Pharaoh.

Moses had announced to Pharaoh, “This is what the Lord says: At midnight tonight I will pass through the heart of Egypt. All the firstborn sons will die in every family in Egypt, from the oldest son of Pharaoh, who sits on his throne, to the oldest son of his lowliest servant girl who grinds the flour. Even the firstborn of all the livestock will die. Then a loud wail will rise throughout the land of Egypt, a wail like no one has heard before or will ever hear again. But among the Israelites it will be so peaceful that not even a dog will bark. Then you will know that the Lord makes a distinction between the Egyptians and the Israelites. All the officials of Egypt will run to me and fall to the ground before me. ‘Please leave!’ they will beg. ‘Hurry! And take all your followers with you.’ Only then will I go!” Then, burning with anger, Moses left Pharaoh.

And Moses said, “Thus says Yahweh, ‘About the middle of the night I will go out through the midst of Egypt, and every firstborn in the land of Egypt will die, from the firstborn of Pharaoh who sits on his throne to the firstborn of the slave woman who is behind the pair of millstones and every firstborn animal. And there will be a great cry of distress in all the land of Egypt, the like of which has not been nor will be again. But against all the Israelites, from a man to an animal, a dog will not even bark, so that you will know that Yahweh makes a distinction between Egypt and Israel.’ And all of these your servants will come down to me and bow to me, saying, ‘Go out, you and all the people who are at your feet.’ And afterward I will go out.” And he went out from Pharaoh in great anger.

And Moses said, Thus saith the Lord, About midnight will I go out into the midst of Egypt: And all the firstborn in the land of Egypt shall die, from the firstborn of Pharaoh that sitteth upon his throne, even unto the firstborn of the maidservant that is behind the mill; and all the firstborn of beasts. And there shall be a great cry throughout all the land of Egypt, such as there was none like it, nor shall be like it any more. But against any of the children of Israel shall not a dog move his tongue, against man or beast: that ye may know how that the Lord doth put a difference between the Egyptians and Israel. And all these thy servants shall come down unto me, and bow down themselves unto me, saying, Get thee out, and all the people that follow thee: and after that I will go out. And he went out from Pharaoh in a great anger.
