This is a bit delayed, it being the fourth night of Chanukah, but better late than never!
I saw this poster hanging in the lobby of my mother’s apartment building when we went to visit her for Thanksgiving. I wasn’t aware there were enough Jewish tenants living there for the management to recognize the holiday. Maybe they put up signs for every major religious holiday? Regardless, it was very well done and a nice gesture.
Chanukah is a commemoration of the reconquest of Jerusalem by the Maccabees and the rededication of the Temple to God. The oil they had available to light the menorah in the Temple was only enough for one day, but they lit it anyway, while they got to work making more, which was an eight-day process of pressing and purifying. According to tradition, the oil vessel miraculously refilled itself every night allowing them to keep the menorah burning for all eight nights. That’s why Jews today light a menorah each night of the holiday, in commemoration of not just the rededication but the miracle of the oil.
