What was the purpose of the Pesach Mitzrayim? Why was a sacrifice called for proceeding the exodus from Egypt? And why did the Pesach Mitzrayim require all the various preparatory stages unique to Pesach Mitzrayim (which are not practised for Pesach Dorot)? Midrashic sources such as the Mekhilta and the Midrash Lekach Tov  respond to these questions and raise other ones. We arrive at an understanding of the purpose of the unique features of Pesach Mitzrayim: to identify with the God of Israel; to break ties with Egyptian culture and strengthen the Israelite identity.
