Kiddush

Kiddush (/ˈkɪdɪʃ/; Hebrew: קידוש‎ [ki'duʃ]), literally, "sanctification," is a blessing recited over wine or grape juice to sanctify the Shabbat and Jewish holidays. Additionally, the word refers to a small repast held on Shabbat or festival mornings after the prayer services and before the meal.

Significance

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.

Reciting kiddush before the meal on the eve of Shabbat and Jewish holidays is thus a commandment from the Torah (as it is explained by the Oral Torah). Reciting kiddush before the morning meal on Shabbat and holidays is a requirement of rabbinic origin. Kiddush is not usually recited at the third meal on Shabbat, although Maimonides was of the opinion that wine should be drunk at this meal as well.
