What's Happening in the Book of Exodus?

The first 12 days of the month of Nissan, which is in the springtime, is the Babylonian New Year. And so it was this 12-day ritual of bringing out Marduk, letting his idol see what is going on in the city. He basically takes it all in and he judges the city accordingly. After this festival ends, two days later, on the 14th of Nissan, is when Passover begins. So commemorating Moses and the existence from Egypt. It's not how Moses is the status change. It's that it actually does.
