Over the years the custom of celebrating Hanukkah with lights developed. Thus, historian Josephus reports that by the first century C.E., Hanukkah was also known as the Festival of Lights. However, the origin of this custom is unclear. One story alleges that it commemorates a miracle that occurred when the temple was rededicated. According to this story, when it came time to relight the lampstand in Jehovah’s temple, although there was only enough ceremonially clean oil for one day, it miraculously lasted for eight days.b
