Today, we celebrate the day when Jesus processed triumphally into Jerusalem. His followers waved palms in salute. Shortly after this, He would go berserk at the Temple, overturning the tables of the money changers and merchants who were financially exploiting the pilgrims and turning the Temple into a den of robbers. Shortly after that, he would be crucified.
