At the beginning of the Seder we announce:
This is the bread of affliction that our fathers ate in the land of Egypt. Whoever is hungry, let him come and eat; whoever is in need, let him come and conduct the Seder of Passover. This year we are here; next year in the land of Israel. This year we are slaves; next year we will be free people.
-From the Passover Haggadah
