Exodus 12:12-14

Lexham English Bible

¹² “And I will go through the land of Egypt during this night, and I will strike all of the firstborn in the land of Egypt, from human to animal, and I will do punishments among all of the gods of Egypt. I am Yahweh. ¹³ And the blood will be a sign for you on the houses where you are, and I will see the blood, and I will pass over you, and there will not be a destructive plague among you when I strike the land of Egypt.

¹⁴ “And this day will become a memorial for you, and you will celebrate it as a religious feast for Yahweh throughout your generations; you will celebrate it as a lasting statute.
