Followers of this ancient middle eastern religion which counts 14 million followers, believe in the holy day of Sabbath (also known as Shabbat) this holy day begins at nightfall on Friday and lasts until nightfall on Saturday The idea of a day of rest comes from the Hebrew Bible story of the Creation: G-d rested from creating the universe on the seventh day of that first week, so like g-d Jews rest from work on the Sabbath.
One of the most important ritual that is performed during Sabbath is the lighting of the candles. This is a h ritual performed 18 minutes after sundown by the woman of the house in which she lights up at least 2 candles. After lighting the candles, a blessing is recited over the candles.
