6You must keep it until the fourteenth day of the month, when the whole assembly of the congregation of Israel will slaughter the animals at twilight.
7They are to take some of the blood and put it on the sides and tops of the doorframes of the houses where they eat the lambs.
8They are to eat the meat that night, roasted over the fire, along with unleavened bread and bitter herbs.
9Do not eat any of the meat raw or cooked in boiling water, but only roasted over the fire— its head and legs and inner parts.
— Exodus 12:6-9
