40-41 The Lord's people left Egypt exactly four hundred and thirty years after they had arrived.
42 On that night the Lord kept watch for them, and on this same night each year Israel will always keep watch in honour of the Lord.
43 The Lord gave Moses and Aaron the following instructions for celebrating Passover:No one except Israelites may eat the Passover meal.
44 Your slaves may eat the meal if they have been circumcised,
45 but no foreigners who work for you are allowed to have any.
46 The entire meal must be eaten inside, and no one may leave the house during the celebration.No bones of the Passover lamb may be broken.
47 And all Israelites must take part in the meal.
