G-d tells Moshe that He is hardening Pharaoh's heart so that through miraculous plagues the world will know for all time that He is the one true G-d. Pharaoh is warned about the plague of locusts and is told how severe it will be. Pharaoh agrees to release only the men, but Moshe insists that everyone must go. During the plague, Pharaoh calls for Moshe and Aharon to remove the locusts, and he admits he has sinned. G-d ends the plague but hardens Pharaoh's heart, and again Pharaoh fails to free the Jews. The country, except for the Jewish People, is then engulfed in a palpable darkness. Pharaoh calls for Moshe and tells him to take all the Jews out of Egypt, but to leave their flocks behind. Moshe tells him that not only will they take their own flocks, but Pharaoh must add his own too. Moshe tells Pharaoh that G-d is going to bring one more plague, the death of the firstborn, and then the Jews will leave Egypt. G-d again hardens Pharaoh's heart, and Pharaoh warns Moshe that if he sees him again, Moshe will be put to death. G-d tells Moshe that the month of Nissan will be the chief month. The Jewish people are commanded to take a sheep on the 10th of the month and guard it until the 14th. The sheep is then to be slaughtered as a Pesach offering, its blood put on their door-posts, and its roasted meat eaten. The blood on the door-post will be a sign that their homes will be passed-over when G-d strikes the firstborn of Egypt. The Jewish People are told to memorialize this day as the Exodus from Egypt by never eating chametz on Pesach. Moshe relays G-d's commands, and the Jewish People fulfill them flawlessly. G-d sends the final plague, killing the first born, and Pharaoh sends the Jews out of Egypt. G-d tells Moshe and Aharon the laws concerning the Pesach sacrifice, pidyon haben (redemption of the first born son) and tefillin.
A Sign For Our Times
"And it [tefillin] shall be a sign upon your arm, and an ornament between your eyes, for with a strong hand G-d took us out from Egypt." (13:16)
There was once a child prodigy who, at the age of three, could play Rachmaninoff better than the best.
A concert was arranged for her to play in public. Months before, posters and TV advertisements proclaimed that she would perform for one concert, and one concert only.
In order that this once in a lifetime event would not be forgotten, special mementos of the concert would be sold. For example, a tiny white concert piano on a bracelet, or a tiara with a piano on it.
The morning after the concert, the newspapers fell over themselves trying to find superlatives to describe the performance.
About a month later, a couple of louts who had missed the show turned up at the child's home and demanded a "command" performance.
"Yeah, we know everyone says she was great. We read the newspapers and all, but we don't believe it. If you bring her down from her bedroom now and get her to perform here in your sitting room on this grand piano, then we'll believe she's as good as everyone says she is; if not we don't believe..."
When G-d created the world, there was no doubt that it was He who had brought everything into existence, that He knew all that was going on in the world, and that He was involved in the smallest event that happens in this world.
From the time of Enosh, Adam's grandson, people started to make mistakes about G-d. Some people denied that there was a G-d at all.
Others conceded the existence of a Divine Power, but said that He was so removed and exalted that He only had knowledge of the spiritual realm, but didn't know what was going on down in this world.
Yet a third group admitted that G-d knows what is happening in the lower realms, but He isn't interested in what we do. In other words, He created the Universe, and then, as it were, went off to play golf.
G-d decided once and for all to quash these mistakes. He would bring a series of miraculous events that would show, by altering the course of nature, that He creates nature.
Not only this, but He would take a nation out of the midst of another nation and make them His people. This would show that not only is He aware of what transpires in this world, but He cares and interacts with Mankind.
G-d would do this only once, because by performing these miracles, He would remove the ability of man to have freedom of choice to believe in Him or not, and the purpose of Creation was the existence of a being, Man, who has free will to believe or not.
This is the story of the Exodus. G-d took the Jewish People out of Egypt to prove that He is alive and well and the world is living in Him!
In order that we should not forget this once-and-once-only re-orchestration of nature, He gave us souvenirs of the "concert" such as a mezuza to put on our doors and tefillin to bind on our arms. Someone who has these reminders will go through his life as though he had a string tied around his pinkie and will never forget.
Not only that, G-d made it incumbent on every generation to pass-over - to recreate the events of this great concert of nature in every generation at a Seder so that each generation would know that it had actually happened. Parents don't lie to their children about things of importance.
For this reason, G-d will not perform at the whim of every boor who comes along and claims that he doesn't believe there was a concert at all. There are millions of fans who still have their tiny white concert pianos carefully handed down from generation to generation to prove the others wrong.
