Say to the children of Israel, If any one of you or of your families is unclean because of a dead body, or is on a journey far away, still he is to keep the Passover to the Lord:
Take no leavened bread with it; for seven days let your food be unleavened bread, that is, the bread of sorrow; for you came out of the land of Egypt quickly: so the memory of that day, when you came out of the land of Egypt, will be with you all your life.
