Write a 400-word essay on the following topics using at least three sources to support your answers:The ideas of Oneg Shabbos (delighting in the Sabbath) and Kavod Shabbos (honoring the Sabbath) are indeed very ancient. What is their source (is there a Torah reference, or do we derive it from the prophets?), and how does one fulfill these mitzvos? (Bring an example for both Kavod and Oneg) How does lighting Shabbos candles interface with these two ideas? Can lighting Shabbos candles be categorized under one of these ideas or both? What is the concept of rest on Shabbos, and how does the prohibition of Muktzeh safeguard it? (Why was mukzeh enacted?)During the week, we obtain holiness via mitzvos like giving tzedakah, visiting the sick, doing chesed, and making prayer requests for our general material welfare. Doing these mitzvos elevates our mundane activity into something holy. On Shabbos, these activities are either forbidden or severely limited. The Torah says that Shabbos is kodesh (holy) because we are not permitted to do melacha on Shabbos. The Mishkan was also “holy,” and its sanctity was created by the actions of those who built it. These holy actions are the 39 prohibited melachos of Shabbos. What constitutes holiness on Shabbos?  Lastly, elaborate on how Shabbos plays a role in the Jewish Community. What would be lacking from the Shabbos experience if one were alone? Would one be able to fully observe Shabbos in such a scenario? Explain why or why not.
