And Moses said, Thus saith the Lord, About midnight will I go out into the midst of Egypt: (11:4)

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. (11:5)

And there shall be a great cry throughout all the land of Egypt, such as there was none like it, nor shall be like it any more. (11:6)

But against any of the children of Israel shall not a dog move his tongue, against man or beast: that ye may know how that the Lord doth put a difference between the Egyptians and Israel. (11:7)

And ye shall observe [the feast of] unleavened bread; for in this selfsame day have I brought your armies out of the land of Egypt: therefore shall ye observe this day in your generations by an ordinance for ever. (12:17)

And it came to pass, that at midnight the Lord smote all the firstborn in the land of Egypt, from the firstborn of Pharaoh that sat on his throne unto the firstborn of the captive that [was] in the dungeon; and all the firstborn of cattle. (12:29)

And Pharaoh rose up in the night, he, and all his servants, and all the Egyptians; and there was a great cry in Egypt; for [there was] not a house where [there was] not one dead. (12:30)
