When you plan a trip that you know will take a long time and there will be very little opportunity on the way to obtain food supplies you would naturally make the necessary arrangements You would buy what you think you will need and you will pack what you imagine will be useful during your trip.
When Bnei Israel left their enslavement behind and started on their journey to the Promised Land, the Torah says: VEGAM TZEDAH LO ASU LAHEM, “…nor had they made provisions for themselves.” (Ex. 12,39) They were promised by Moshe that they are going to be redeemed. They knew they had a long journey before them. Why did they not prepare?
A Rabbi once suggested that the verse that follows the one quoted above offers the answer. We are told immediately that the Jews sojourned in Egypt 430 years. Why are these two verses placed near each other? The suggestion made is that after spending so much time in Galut they could not really believe that they are going to be redeemed.
There are people today, even pious observant Jews, who think that modern Israel is not the true redemption in our times. After 2000 years in the Diaspora they cannot bring themselves to believe that Israel is finally restored.
