Exodus 12:10-12

New Revised Standard Version, Anglicised

¹⁰ You shall let none of it remain until the morning; anything that remains until the morning you shall burn. ¹¹ This is how you shall eat it: your loins girded, your sandals on your feet, and your staff in your hand; and you shall eat it hurriedly. It is the passover of the Lord. ¹² For I will pass through the land of Egypt that night, and I will strike down every firstborn in the land of Egypt, both human beings and animals; on all the gods of Egypt I will execute judgements: I am the Lord.
