“Speak to the sons of Israel, saying, ‘If any one of you or of your generations becomes unclean because of a dead person, or is on a distant journey, he may, however, celebrate the Passover to the Lord.
On the fourteenth day of this month, at twilight, you shall celebrate it at its appointed time; you shall celebrate it in accordance with all its statutes and all its ordinances.”
You shall not eat leavened bread with it; for seven days you shall eat unleavened bread with it, the bread of affliction (for you came out of the land of Egypt in a hurry), so that you will remember the day when you came out of the land of Egypt all the days of your life.
