Exodus 12:27-29

Amplified Bible, Classic Edition

²⁷ You shall say, It is the sacrifice of the Lord’s Passover, for He passed over the houses of the Israelites in Egypt when He slew the Egyptians but spared our houses. And the people bowed their heads and worshiped.

²⁸ The Israelites went and, as the Lord had commanded Moses and Aaron, so they did.

²⁹ At midnight the Lord slew every firstborn in the land of Egypt, from the firstborn of Pharaoh who sat on his throne to the firstborn of the prisoner in the dungeon, and all the firstborn of the livestock.
