Exodus 12:8-10
8
They shall eat the flesh in that night, roasted with fire, and unleavened bread. They shall eat it with bitter herbs.

Don't eat it raw, nor boiled at all with water, but roasted with fire; with its head, its legs and its inner parts.
10
You shall let nothing of it remain until the morning; but that which remains of it until the morning you shall burn with fire.
