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)

⁹ Let it serve as a sign for you on your hand and as a reminder on your forehead,^[a](A) so that the Lord’s instruction may be in your mouth; for the Lord brought you out of Egypt with a strong hand.
