Exodus 12:28-30 New American Bible (Revised Edition) (NABRE)
28 and the Israelites went and did exactly as the Lord had commanded Moses and Aaron.
Death of the Firstborn. 29 And so at midnight the Lord struck down every firstborn in the land of Egypt, from the firstborn of Pharaoh sitting on his throne to the firstborn of the prisoner in the dungeon, as well as all the firstborn of the animals. 30 Pharaoh arose in the night, he and all his servants and all the Egyptians; and there was loud wailing throughout Egypt, for there was not a house without its dead.
