On Parashat Vayeshev, Joseph and the Maccabees, Emancipation and Chanukkah

Chanukkah begins on the 25th of Kislev because that was the day of the re-dedication of the Temple according to the Book of Maccabees. The coincidence of the Maccabee victory being recorded as having taken place on the Shabbat on which we hear hearing about Joseph is just that, a coincidence.
