A kittel (Yiddish: קיתל, robe) is a special white robe worn by religious Jews during the Days of Awe, on Rosh Hashanah and Yom Kippur, and some also during the Passover Seder. The reason for this is that white symbolizes purity, also causing it to be worn during weddings. Biblically, it is written that "our sins shall be made as white as snow" (Isaiah 1:18). In addition to this usage, the dead are also buried in a kittel, providing simple dress that assures equality for all in death.
