Exodus 12:29-30

Rotherham(i) 29 And it came to pass, at midnight, that Yahweh, smote every firstborn in the land of Egypt, from the firstborn of Pharaoh who sat upon his throne, unto the firstborn of the captive who was in the pit of his prison,––and every firstborn of beasts. 30 Then rose up Pharaoh by night, he, and all his servants, and all the Egyptians, and there arose a great outcry throughout Egypt,––for there was not a house, where there was not one dead.
