<P> Some Hasidic movements hold a tish every Shabbat; others do so only on Jewish holidays . The time at which a tish can be held also differs . For example, Belzer Hasidim conduct their tish both late Friday night and on Saturday afternoon for Seudah Shlishit, while Gerrer Hasidim only have their tish on Saturday afternoon or early evening for Seudah Shlishit . </P> <P> A tish is usually also held on minor holidays such as Lag b'Omer, Hanukkah, Purim, Tu Bishvat, on the minor days (Chol Hamoed) of major festivals such as Sukkos and Pesach, and before and after the fast of Yom Kippur . </P> <P> Hasidim may also visit the tish of another Rebbe, and non-Hasidic Jews often visit a tish also . Non-Jews sometimes visit a tish as well, particularly dignitaries and politicians during a weekday tish such as on Chol HaMoed . </P> <P> The nature of the tish differs from group to group but during the tish, the Hasidim intently and silently watch the rebbe eating the meal and are extremely eager to receive shirayim ("leftovers"), cooked alongside the Rebbe's courses, believing it to be a great merit (zechus) to eat something from the leftovers of a tzadik's meal . Many Hasidim claim that miracles can take place in merit of partaking of the shirayim, such as miraculous healing or blessings of wealth or piety . </P>
