Exodus 12:27-29

Christian Standard Bible

²⁷ you are to reply, ‘It is the Passover sacrifice^(A) to the Lord, for he passed over the houses of the Israelites in Egypt when he struck the Egyptians, and he spared our homes.’” So the people knelt low and worshiped. ²⁸ Then the Israelites went and did this; they did just as the Lord had commanded Moses and Aaron.

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.^(B)
