Why do Jews eat matza on Passover?
The book of Exodus commands the Jews to eat matza. The bible says that at the time of the exodus, the Jews left Egypt in such a hurry that their dough did not have time to rise. To commemorate this, they eat unleavened bread, or matza, every Passover.

Many Jews eat matza today, even if they do not believe that they obeying a divine command. They may eat matza as a means of connecting with their Jewish heritage, or because they are participating in a seder, the traditional Passover meal, or just because they like the taste.
