Thematic Bible: Passing over the first-born

For I will pass through the land of Egypt this night and will smite all the firstborn in the land of Egypt, both among man and beast; and against all the gods of Egypt I will execute judgments: I am the LORD. And this blood shall be to you for a sign upon the houses where ye are; and when I see the blood, I will pass over you, and the plague shall not be upon you to destroy you, when I smite the land of Egypt.
