The Sabbath is the seventh day of the week. It is a day of rest for Jews because after six days of creation, G-d rested on the seventh day. It is known to be a day of "don't"s (don't drive, don't use your phone, don't cook, etc.), but it is also a day of many "do"s such as go to synagague, make kiddush on wine and a festive meal, study Torah and spend quality time with family and friends!
