Exodus 12:8-11
12:8 They will eat the meat the same night; they will eat it roasted over the fire with bread made without yeast and with bitter herbs.
12:9 Do not eat it raw or boiled in water, but roast it over the fire with its head, its legs, and its entrails.
12:10 You must leave nothing until morning, but you must burn with fire whatever remains of it until morning.
12:11 This is how you are to eat it – dressed to travel, your sandals on your feet, and your staff in your hand. You are to eat it in haste. It is the Lord’s Passover.
