"הַנֵּרוֹת הַלָּלוּ אָנוּ מַדְלִיקִין עַל הַנִּסִּים וְעַל הַנִּפְלָאוֹת וְעַל הַתְּשׁוּעוֹת וְעַל הַמִּלְחָמוֹת
שֶׁעָשִׂיתָ לַאֲבוֹתֵינוּ בַּיָּמִים הָהֵם בַּזְּמַן הַזֶּה"
"Hanukkah, Hanukkah A beautiful holiday" says the famous song by Levin Kipnis. And indeed this holiday is beautiful and enlightening, homely and warm. At exactly the moment when the sun sets, the members of the household gather for a magical family hour, the candles are lit, the pancakes are stirring in the pan, the smell of olive oil in the air and the precious light of candles.
The Chanukia is one of the most popular Judaica objects. A year after the day Beit Hamikdash was cleansed in 164 BCE and until our day, year after year during Hanukkah, we light candles with a Chanukia.
All oils and wicks are kosher to light the candles but it is appropriate to light the menorah with olive oil, because with this oil they lit the Menorah in Beit Hamikdash where the miracle happened. The accepted custom is that each member of the household lights a Hanukkah candle so that from each window we see the lit candles of the household members.
