“On that night I will go through the land of Egypt, killing every first-born male, both human and animal, and punishing all the gods of Egypt. I am the Lord.
When the king of Egypt was stubborn and refused to let us go, the Lord killed every first-born male in the land of Egypt, both human and animal. That is why we sacrifice every first-born male animal to the Lord, but buy back our first-born sons.
But I will pass judgment on the people that they will serve, and afterward your descendants will come out of that country and will worship me in this place.’
