When the Rabbis divided the Torah into its 54 parashiyot (portions), they generally arranged for each portion to begin with a unique or otherwise significant word that would in some way summarize major themes of the entire section.
You shall each revere your mother and your father, and keep My sabbaths: I the Eternal am your God. (Leviticus 19:3)
When someone asked a friend of mine what his daughter enjoys most about living in Israel, he explained that she loves the way the country’s secular rhythms synch seamlessly with religious time in a way that doesn’t happen in North America. By way of example, he described Shabbat and holidays as characterized by closed shops, quiet streets, and low-key television programming.
