Exodus 11:4–5

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.

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.

So Moses said, “This is what the Lord says: About midnight I will go throughout Egypt, and every firstborn male in the land of Egypt will die, from the firstborn of Pharaoh who sits on his throne to the firstborn of the servant girl who is at the grindstones, as well as every firstborn of the livestock.

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.

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 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.
