'Passover' in the Bible
“The Israelites are to observe the Passover at its appointed time.
But there were some men who were unclean because of a human corpse, so they could not observe the Passover on that day. These men came before Moses and Aaron the same day
“Tell the Israelites: When any one of you or your descendants is unclean because of a corpse or is on a distant journey, he may still observe the Passover to the Lord.
they may not leave any of it until morning or break any of its bones. They must observe the Passover according to all its statutes.
“But the man who is ceremonially clean, is not on a journey, and yet fails to observe the Passover is to be cut off from his people, because he did not present the Lord’s offering at its appointed time. That man will bear the consequences of his sin.
“If a foreigner resides with you and wants to observe the Passover to the Lord, he is to do so according to the Passover statute and its ordinances. You are to apply the same statute to both the foreign resident and the native of the land.”
“The Passover to the Lord comes in the first month, on the fourteenth day of the month.
They departed from Rameses in the first month, on the fifteenth day of the month. On the day after the Passover the Israelites went out triumphantly in the sight of all the Egyptians.
