We are commanded to feed the hungry all year long. Only on Pesach, however, do we announce: let all who are hungry come and eat. Why? Because sharing with others is one of the ways to remember that we were slaves in Egypt. Rejoice before the LORD your God…the sojourner and the orphan and the widow who are in your midst… you shall remember that you were a slave in Egypt. The announcement to let all who are hungry come and eat is there to remind us of the time that we went hungry in Egypt.
