Exodus 11:4-7 ▼

4 So Moses said, “Thus says Yahweh, ‘About midnight I am going out into the midst of Egypt,

5 and all the firstborn in the land of Egypt shall die, from the firstborn of the Pharaoh who sits on his throne, even to the firstborn of the servant-girl who is behind the millstones; and all the firstborn of the cattle.

6 Moreover, there shall be a great cry in all the land of Egypt, such as there has not been before and such as shall never be again.

7 But for any of the sons of Israel a dog will not even bark, whether against man or beast, that you may know how Yahweh makes a distinction between Egypt and Israel.’
