Exodus 11:5-7

Holman Christian Standard Bible

⁵ 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 behind the millstones, as well as every firstborn of the livestock. ⁶ Then there will be a great cry of anguish through all the land of Egypt such as never was before, or ever will be again. ⁷ But against all the Israelites, whether man or beast, not even a dog will snarl,^[a] so that you may know that Yahweh makes a distinction between Egypt and Israel.
