The Holy Temple in Jerusalem is the heart of the Jewish nation. The First (Solomon's) Temple was destroyed by the Bebylonians. The Second was defiled by the Greeks, rededicated, refurbished by King Herod, and finally destroyed by the Romans. The yet-to-be-built Third Temple is prayed for every day by Jews in Israel and all over the world.
