The word for Egypt, Mitzrayim, connotes restraints or borders, a narrow place. A Jew must realize that every day of his life, G-d not only releases him from the shackles of Egypt (‘takes him out’), but gives him the opportunity to break through an even higher and more subtle level of limitation (‘lifts him’). G-d gives a Jew the ability to go beyond his personal physical limits and even beyond nature. This is alluded to by the expression ‘widening our mouths,’

The Jew… has the ability and responsibility to complete G-d’s creation, to go beyond what he believes possible and make the world whole. We accomplish this by widening our mouths. With the use of our mouths to praise G-d, learn Torah, pray, and communicate positive messages to others, we complete the world. In this way we fulfill our purpose in coming to this world, by transforming nature and making the world a better place in which to live.”
