Most commentators see 'Lebanon' as a powerful symbol for the Temple in Jerusalem, which was famously built with its cedars. This verse is understood as a prophecy of the Temple's destruction. Scholars like Albert Barnes and John Gill note that ancient Jewish tradition and the historian Josephus record that the Temple gates mysteriously opened on their own 40 years before its fall in AD 70, an event seen as a direct fulfillment of this prophecy.
