Now the Maccabees returned to Jerusalem to liberate it. They entered the Temple and cleared it of the idols placed there by the Syrian vandals. Judah and his followers built a new altar, which he dedicated on the twenty-fifth of the month of Kislev, in the year 3622.
Since the golden Menorah had been stolen by the Syrians, the Maccabees now made one of cheaper metal. When they wanted to light it, they found only a small cruse of pure olive oil bearing the seal of the High Priest Yochanan. It was sufficient to light only for one day. By a miracle of G-d, it continued to burn for eight days, till new oil was made available. That miracle proved that G-d had again taken His people under His protection. In memory of this, our sages appointed these eight days for annual thanksgiving and for lighting candles.
