Why do we eat matzah on Pesach? It's a very basic, simple and obvious question, so it should have a very basic, simple and obvious answer, right? The usual answer is the one given in the Haggadah. The Torah commands us to eat matzah on Pesach in commemoration of the Bnei Yisrael being rushed out of Egypt so quickly that their dough did not have time to rise. It's commonly assumed that this is nothing more than a paraphrase of what the Torah itself says. But why would this make matzah so very important? And is it indeed necessarily what the Torah says?
