The Exodus

²⁹ Now at midnight the Lord struck every firstborn male in the land of Egypt, from the firstborn of Pharaoh who sat on his throne to the firstborn of the prisoner who was in the dungeon, and every firstborn of the livestock.^(A)

¹⁵ When Pharaoh stubbornly refused to let us go, the Lord killed every firstborn male in the land of Egypt, both the firstborn of humans and the firstborn of livestock. That is why I sacrifice to the Lord all the firstborn of the womb that are males, but I redeem all the firstborn of my sons.”
