This year Christmas and Hanukkah fall on the very same day. Curiously Hanukkah, a Jewish holiday, is not mentioned in any book of the Tanakh (Hebrew Bible). But the story that led to Hanukkah, also known as the Festival of Lights, is told in the first and second book of the Maccabees, which is part of the Old Testament of the Catholic and Orthodox Church.
