Exodus 12:9-11

King James Version

⁹ Eat not of it raw, nor sodden at all with water, but roast with fire; his head with his legs, and with the purtenance thereof.

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.
