The Jewish Calendar and Holidays (incl. Sabbath): The Sabbath: Shabbos Candles:
Why do we light candles on Shabbos?
Shabbos lights aren't mentioned in the Bible, but they are
a natural part of the enjoyment of Shabbos (Isaiah 58:13).
No doubt there were sectarians who prohibited Shabbos lights
based on their interpretation of Ex.35:3; that's why the
Rabbis have emphasized their importance, since at least
Second Temple times.
