It was customary for virgins to be a part of marriage banquets. Since the wedding procession was usually at night, many would carry torches or lamps. However, no one would know the time that the bridegroom would arrive with the bride, until the herald comes crying. At their arrival, those who are with the crowd/procession, will be able to slip inside, and the doors are closed immediately. As a result, those who are late will not be allowed to enter.
