What is the meaning of the phrase "Next year in Jerusalem" or in Hebrew, shana habaa b'Yerushalayim that we say at the end of the Passover seder? "Next year in Jerusalem" means that all Jews should actually be living in their homeland of Israel where they can come to Jerusalem. It is of course very important to note though that the Jerusalem we are referring to is Jerusalem as it is ideally meant to be — with the Temple, the Sanhedrin and a Jewish Monarch! Even we here in Israel and in Jerusalem say "Next year in Jerusalem!"
Okay, you say, but with the world as it is right now, how can we possibly think that Jerusalem can return to what it once was thousands of years ago? The answer to this question is rather deep and something better left to others, but I can tell you that this longing and the belief that we can return to this ideal is one of the foundations of Judaism, and one of the reasons why the Jewish people have survived over thousands of years. And just by the way, this idea of never giving up hope on the human race, and always striving for peace is one of the gifts that the Jewish people have actually bestowed upon the world.
Connected to the idea of "next year in Jerusalem" is the phrase "remember Jerusalem" , seen in the remember Jerusalem wall hanging above, which is really the same concept, only something that we think about every day, as opposed to at the end of the seder. Okay, then so what does "remember Jerusalem" mean? The words, are taken from tehillim (psalms) written by King David and refer to the purpose of Jerusalem's existence, namely as a spiritual capital of the world.
It is true, the hebrew words on the plaque don't actually say "remember Jersualem", they say "if you forget Jerusalem" but for some reason that is how it is translated, I guess just to be positive about it, which is certainly legitimate. What else does the plaque say? Happy to tell you, just keep on reading!
