 The Hallel was recited during the meal, and when the lamb had been eaten the meaning of the custom was explained, and the story of the Exodus was told.The Passover sacrifice belongs to the category of "zevachim" that are eaten by the owner (similar to "shelamim)", thus forming one of the sacrifices in which the meal is the principal part and indicates the community between God and man.It is really a house or family sacrifice, and each household is regarded as constituting a small community in itself, not only because the lamb is eaten at home, but also because every member of the family is obliged to partake of the meal, although each male must be circumcised in order for it to be permissible for him to eat, and all must be ritually pure.
