Exodus 11:5-7

World English Bible

⁵ and all the firstborn in the land of Egypt shall die, from the firstborn of Pharaoh who sits on his throne, even to the firstborn of the female servant who is behind the mill, and all the firstborn of livestock. ⁶ There will be a great cry throughout all the land of Egypt, such as there has not been, nor will be any more. ⁷ But against any of the children of Israel a dog won’t even bark or move its tongue, against man or animal, that you may know that Yahweh makes a distinction between the Egyptians and Israel.
