They said the Messiah was coming, and many members of the Habad religious movement believed it and arrived at the Tel Aviv basketball stadium to greet him. Their Messiah is supposedly the late Rabbi Menachem Schneerson, seen in the poster above. His posters can be seen everywhere, including one of the first pictures you see when you arrive in Israel, at the airport. He is portrayed as if he is still alive.
According to some, if all the Jews of Israel kept two full Sabbaths, then the Messiah would show up. I think we have a long wait..
