Have you ever grappled with one of those wooden puzzle boxes that has a secret compartment? If you manipulate the different pieces correctly, a hidden drawer pops open and you find the concealed prize.
This type of puzzle can be extremely frustrating. I was once handed such an item at a dinner party. After a while, I became convinced that there was no answer. The whole thing was simply a sadistic game. At that point, the friend who gave me the game took back the box and showed me exactly how to solve the puzzle. Once I knew how it was quite simple.
In a similar manner, a full 30% of the Book of Exodus is taken up by a long and detailed description of how Israel got out of Egypt. We Jews read those Torah portions every single year, and in addition, once each year we actually live out the entire experience in a ceremony known as the Passover Seder.
