The men drawing water for the special matzah baked right before Passover, wished each other well: "L'shanah haba'ah biyrushalayim, Next year in Jerusalem."
Rabbi Shalom of Belz heard them talking and exclaimed: "Why should we wait a whole year till next year? Moshiach can come to redeem us immediately, and we'll bake matzah tomorrow afternoon in Jerusalem with this very water, and eat our matzah in Jerusalem!"
