"We were slaves to Pharaoh in Egypt, and the L-rd, our G-d, took us out from there with a strong hand and with an outstretched arm. If the Holy One, blessed be He, had not taken our fathers out of Egypt, then we, our children and our children's children would have remained enslaved to Pharaoh in Egypt. Even if all of us were wise, all of us understanding, all of us knowing the Torah, we would still be obligated to discuss the exodus from Egypt; and everyone who discusses the exodus from Egypt at length is praiseworthy."
