In Judaism, marriage is a complex ritual that varies according to the couple's and their community's relationships with Judaism. In many communities, especially Ashkenazic ones, the wedding is preceded by an aufruf: on the Shabbat (Saturday) before the wedding, the groom is called to the Torah to receive an honor and a blessing, after which the congregation sings to them and pelts them with candy, representing a sweet life. Immediately before the wedding proper, two witnesses sign a ketubah, or marriage contract, which details the groom's obligations toward the bride (home, food, clothing, sex, faithfulness). In egalitarian movements, the wording is adjusted and the bride and groom also sign. The ketubah is frequently a beautiful, illuminated document, and the couple will often display it in their home. The wedding ceremony takes place under a chuppah, a canopy supported on four poles, symbolizing the couple's home. The bride's face is veiled — recalling Genesis, in which Laban tricked Jacob into marrying Leah rather than Rachel by having the bride veiled at the ceremony, but to prevent such an occurrence, the groom removes the veil to verify that he will marry the correct person. The bride walks around the groom three or seven times. The groom presents the bride with an object of value (typically a ring), and in egalitarian weddings, vice versa. Seven blessings (Hebrew: sheva b'rachot) formalize the marriage. The groom breaks a glass (or in the egalitarian movements, the bride and groom may break a glass together) to remind the community that even at a joyous occasion there is still sorrow (particularly with respect to the destruction of the Temple in Jerusalem). The wedding is followed by a festive meal and party. Dancing is common, especially the hora, and it is traditional to lift the bride and groom on chairs. Traditionally, a special version of birkat ha-mazon (grace after meals) is recited.
