In Egypt, Pharaoh was stubborn and refused to let us leave. So the Lord killed every firstborn in all the land. (The Lord killed the firstborn males—animal and human.) That is why I give every firstborn male animal to the Lord, and that is why I buy back each of my firstborn sons from him.’
“Tonight I will go through Egypt and kill every firstborn man and animal in Egypt. In this way I will judge all the gods of Egypt and show that I am the Lord.
Moses prepared the Passover and spread the blood on the doorways of the people of Israel, so that the angel of death would not kill their firstborn sons. Moses did this because he had faith.
