Exodus 12:6-10

6You are to keep it until the fourteenth day of this month; then the whole assembly of the community of Israel will slaughter the animals at twilight.

7They must take some of the blood and put it on the two doorposts and the lintel of the houses where they eat them.

8They are to eat the meat that night; they should eat it, roasted over the fire along with unleavened bread and bitter herbs.

9Do not eat any of it raw or cooked in boiling water, but only roasted over fire — its head as well as its legs and inner organs.

10You must not leave any of it until morning; any part of it left until morning you must burn.
