Exodus 12:8-10

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.
