Exodus 11:5

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 behind the handmill , and all the firstborn of the cattle .

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.

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.
