Kidush (Hebrew: קידוש, literally, "sanctification") is a blessing recited over wine or grape juice to sanctify the Shabbat or a Jewish holiday. The Torah refers to two requirements concerning Shabbat - to "keep it" and to "remember it" (shamor and zakhor). Jewish law therefore requires that Shabbat be observed in two respects. One must "keep it" by refraining from thirty-nine forbidden activities, and one must "remember it" by making special arrangements for the day, and specifically through the kiddush ceremony.
