A Tish, also tische (Yiddish: טיש, lit. 'table', pl. טישן, tischn) is a Shabbat or holiday gathering for Hasidic Jews around their Rabbi or "Rebbe". In Chabad, a tische is called hitva'adut (התועדות). It may consist of speeches on Torah subjects, singing of melodies known as niggunim (singular niggun) and zemirot ("hymns"), with refreshments being served. Hasidim see it as a moment of great holiness.
Within Hasidic Judaism, a tische refers to any joyous public celebration or gathering or meal by Hasidim at a "table" of their Rebbe. Such a gathering is staged around the blessing of Melchizedek-themed "setting of the table" and so is often referred to in Hebrew as Arichat HaShulchan (עריכת השולחן). Bread and wine are essential elements.
