The Mitzvah is a candle and the Torah is light. The word Hanukka can be divided into two words חנו , כ”ה The miracle of the light appeared on the 25th day of the month of Kislev. The word light is the 25th word of the Torah. The Greeks sought to eliminate Torah, and made three specific decrees against Brit Milah, Shabbat, and Rosh Chodesh. Hanukka is at the end of the month of Kislev so that it can contain a Shabbat and a Rosh Chodesh [Ed. and the eight days is also a reference to Brit Milah.] And much much more.
