During the Sabbath, Jews must walk in a way which differs from their regular way of walking during the rest of the week. (…) Furthermore, during the Sabbath, they are supposed to wash themselves in a distinct manner, to sit in a particular dignified way, and even to move things in a special manner which is characteristic of the Sabbath alone (...) Finally, in order to highlight the contrast between sacred time and profane time, they must even talk during the Sabbath in a manner which would differ from the way they talk on regular days. [Zerubavel, Hidden Rhythms (1985: 100-103)]
