Chanukah: Continuing the Celebration

Two questions:
how do we preserve the message of Chanukah throughout the year?
Secondly, I was studying last week’s Torah portion, and was bothered by a question. When relating the story of Joseph and his brothers, the Torah says that they threw him into a pit, “…the pit was empty, no water was in it”. I have always been taught that the Torah doesn’t use extra words; if the pit was empty, obviously there’s no water in it. Isn’t this statement redundant?
