The Ribono Shel Olam gives over the 4 terms of redemption to Moshe to be brought back to the Jewish people. One of the terms is v’hotzei eschem mitachas sivlos mitrayim. Rebbi Menachem Mendel of Kotzk explains the meaning of sivlos mitzrayim. He says that it comes from the word savlanut (patience). Moshe is teaching klal yisroel a message of change. They have become too accustomed to their current circumstances. Change can only come with a new and fresh outlook, with a willingness to rise above the status-quo and compromised circumstances. G-d has granted them an infusion of spirit and strength to break through the shackles of servitude and that will allow them to experience personal and national redemption.
