I just posted this devar torah for Chanukah on JSpot. It's a condensed version of the Lunch-and-Learn that I taught last Shabbat at Hadar. (If you can get your hands on a copy of Pesikta deRav Kahana, I recommend reading the whole story. It's section 1, and it's really good.)
That same morning at Hadar, General Anna gave this devar torah, inspired in part by this Arlo Guthrie concert that we both attended.
Tonight is both the winter solstice and Rosh Chodesh Tevet! So it really is the darkest time of the year: the shortest period of daylight, and the darkest night. It will only get brighter after this.
