Kazan, I don't know if you are aware of the story of the Exodus.
God called Moses to lead the Jews out of Israel. When the Pharoh, Ramses I IIRC, refused Moses(his foster brother BTW) request, and mocking of God in the process, God sent a plague. Moses asked that the Jews be freed, 6 more times IIRC, each request was denied and followed by a plague, each plague worse than the last. When Moses last request had been denied, the final plague came. In the form of the Angel of Death. The Jews were instructed to coat their door frames with the blood of a freshly sacrificed lamb, the Angel passed over houses whose door was marked, and entered the houses that were not. The first born of every creature, livestock and humans, died, including the Pharoh's own son. This was the final straw, he released the Jews, and they were virtually chased from Egypt at the point of a sword. The speed of the departure was such that they had to make the bread before it could rise.
The holiday, Passover, celebrates these events, especially the liberation of the Jews. It is a joyous holiday, but the events it memorializes should not be forgotten, it is the point of the holiday after all. BTW, the holiday is over 4000 years old.
