Exodus 12:10-12

Revised Standard Version

¹⁰ And you shall let none of it remain until the morning, anything that remains until the morning you shall burn. ¹¹ In this manner you shall eat it: your loins girded, your sandals on your feet, and your staff in your hand; and you shall eat it in haste. It is the Lord’s passover. ¹² For I will pass through the land of Egypt that night, and I will smite all the first-born in the land of Egypt, both man and beast; and on all the gods of Egypt I will execute judgments: I am the Lord.
