Shabbos: which kind of rejuvenation?[1]
שמור את-יום השבת לקדשו כאשר צוך יקוק אלקיך: וזכרת כי-עבד היית בארץ מצרים וגו’
Safeguard the Shabbos day, to sanctify it, as Hashem your G-d commanded you…[So] you shall remember that you were a slave in Egypt…[2]
The Ten Commandments make two appearances in the Torah. The first is parshas Yisro[3], when the Torah relates how the Jews heard Hashem speak at Mount Sinai. The second is this week’s parsha, where Moshe recounts that monumental event. A careful examination of the two listings will yield some slight but significant differences. Some of the most pronounced is with regards to the mitzvah of Shabbos. There are different themes and details that are chosen in the second instance, which don’t appear in the first. We are adjured to safeguard the Shabbos, instead of simply remembering it[4]. There’s also a focus on the fact that we were slaves in Egypt. What is the Torah highlighting with this connection to the Exodus?
