Parallel
Exodus 12:29
Brenton's English Septuagint · Berean Standard Bible
And it came to pass at midnight that the Lord smote all the first-born in the land of Egypt, from the first-born of Pharao that sat on the throne, to the first-born of the captive-maid in the dungeon, and the first-born of all cattle.
Now at midnight the LORD struck down every firstborn male in the land of Egypt, from the firstborn of Pharaoh, who sat on his throne, to the firstborn of the prisoner in the dungeon, as well as all the firstborn among the livestock.
