From Josephus Antiquities of the Jews — And so Judah and his fellow citizens celebrated the festival of the restoration of the sacrifices of the Temple for eight days, and omitted no sort of pleasure, but everyone feasted upon very rich and splendid sacrifices; and they honored God, and delighted themselves with psalms of praise and the playing of harps. Indeed, they were so very glad at the revival of their customs and, after so long a time, having unexpectedly regained their right to worship, that they made it a law for their posterity that they should keep a festival celebrating the restoration of their Temple worship for eight days. And from that time to this we celebrate this, which we call the Festival of Lights, because, I imagine, beyond our hopes this right was brought to light, and so this name was placed on the festival.
