Exodus 12:10-12

King James Version

¹⁰ And ye shall let nothing of it remain until the morning; and that which remaineth of it until the morning ye shall burn with fire.

¹¹ And thus shall ye eat it; with your loins girded, your shoes on your feet, and your staff in your hand; and ye shall eat it in haste: it is the Lord's passover.

¹² For I will pass through the land of Egypt this night, and will smite all the firstborn in the land of Egypt, both man and beast; and against all the gods of Egypt I will execute judgment: I am the Lord.
