Exodus 12:7–23
They 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. / They are to eat the meat that night, roasted over the fire, along with unleavened bread and bitter herbs. / Do 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.
