Introduction to Mitzvot 197 - 201
The Prohibitions against "Chametz"
The holiday of Pesach marks the Exodus of the Jewish People from Egypt and the birth of our nation.
The Torah speaks about Pesach many times and gives us many Mitzvot which must be followed during Pesach.
One of the most important Mitzvot of Pesach is not to eat or own any "chametz" - leavened dough.
"Chametz" symbolizes something which has risen high; someone who is proud and haughty.
The Egyptians were a conceited and proud people who worshipped idols.
They refused to accept HaShem, the only One G-d.
Indeed, Pharaoh, the king of Egypt asked, "Who is G-d and why should I listen to Him?"
HaShem answered Pharaoh's question by taking the Jews out of Egypt, splitting the Red Sea, and drowning the mighty Egyptian army.
On Pesach, when we remove all our "chametz" we confirm our acceptance and belief in HaShem, the One and only G-d.
The following Mitzvot caution us not to eat or own "chametz" on Pesach.
