Why is it always the woman who starts sabbat?

Answer 1

In Judaism, women are considered the essence of the home, and are spiritually responsible for their families. in fact, According to traditional Jewish Law, a Jew is anyone born of a Jewish mother.

The positive commandment to light the Shabbat candles applies to the entire family, however, women traditionally accepted upon themselves to light the candles on behalf of their entire household. Therefore, it is passed down in Jewish costum that the women will be the ones to light the candles, and bring in the Shabbat. If there is no woman present, a man may light the candles himself, and recite the blessing.

Another reason women light the candles, is to compensate for the sin of Eve. Eve was the first to eat from the Tree of Knoledge which lead to the expulsion from the Garden of Eden, (Genesis:3;23) and brought a darkness into the world. To make up for the sin of the first woman, it is the woman's responsibility to light the candles which bring light into the world.
