The Significance of Matza
"This matza that we eat on Passover-what is its meaning and what is its significance?
The matza is a reminder of the haste with which the Israelites left Egypt. The dough that they were sunbaking on the hot rocks of the Egyptian fields was removed before it could leaven, and so it remained flat."
