Hanukkah (“dedication” in Hebrew) is a Jewish festival that celebrates the rededication of the second temple in 164 B.C. The temple had been made unfit for worship on the twenty-fifth day of Kislev (mid-November to mid-December) in 167 B.C., when the Seleucid king, Antiochus IV (Epiphanes), sacrificed ritually unclean animals to his gods on the Jewish altar. The heroic deeds of the priest Mattathias and his five sons, known as “the Maccabees,” ultimately defeated these Greek-speaking Syrian oppressors of the Jewish community. During the rebellion, the Jewish people rebuilt the sanctuary, purified the temple, and constructed a new altar. They dedicated the altar to God in an eight-day worship service beginning on the twenty-fifth day of Kislev in 164 B.C., exactly three years after it had been defiled
