Exodus 12:12-13 ▼

12 And I will go through the land of Egypt on that night and will strike down all the firstborn in the land of Egypt, both man and beast; and against all the gods of Egypt I will execute judgments—I am Yahweh.

13 And the blood shall 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 shall be no plague among you to destroy you when I strike the land of Egypt.
