Hashem commands in Parashat Ki-Tisa, "Ach Et Shabetotai Tishmoru" – "However, you shall observe my Shabbatot" (31:13). Rashi explains that after Hashem presented the commands regarding the construction of the Mishkan, He emphasized that the work on the Mishkan must be discontinued on Shabbat. The question arises, however, as to why Hashem here commands observing "Shabetotai" – His "Shabbatot." Instead of simply telling us to observe "Shabbat," He uses the plural form, referring to Shabbat as "Shabbatot." Why? A fascinating explanation is offered by the Ha'ketab Ve'ha'kabbala (Rav Yaakov Tzvi Mecklenberg, 1785-1865). He writes that etymologically, the word "Shabbat" has two meanings. First, it denotes "Shebita" – cessation from work. Additionally, the word "Shabbat" refers to "Yishub Ha'da'at" – peace of mind, and clarity. Ha'ketab Ve'ha'kabbala explains that we are commanded to "observe Shabbat" in two senses: by refraining from Melacha (forbidden activity), and by attaining "Yishub Ha'da'at" by experiencing he special Kedusha of Shabbat. The first Shabbat is intended to bring us to the second; we are to refrain from forbidden work for the purpose of reprogramming our minds, resetting our priorities, and refreshing our perspective on life. Throughout the week, we are busy tending to our needs, occupied with our careers, our businesses, and all the many other important things that we need to deal with. With all the frenzy of the workweek, we can so easily forget what this is all about, what the purpose of all this is. On Shabbat, there is an obligation of "Shebita" – to desist from Melacha – so that we can achieve "Yishub Ha'da'at," peace of mind, a clearer perspective on what life is all about, what our priorities ought to be. We spend more time in the synagogue, more time with our families, more time singing Pizmonim and learning Torah, so we can refresh our minds and remind ourselves of what's truly important. On this basis, Ha'ketab Ve'ha'kabbala suggests a novel reading of the Gemara's famous teaching (Shabbat 118b) that if the Jewish People would properly observe "Sheteh Shabbatot" – two Shabbatot – we would be worthy of redemption. This is commonly understood to mean that we would be redeemed if we all observe Shabbat for two weeks. Ha'ketab Ve'ha'kabbala, however, offers a different interpretation, explaining that the Gemara speaks of the two different dimensions of Shabbat observance. We become worthy of redemption if we not only refrain from the forbidden activities on Shabbat, but also experience the weekly "reset," gaining a new perspective on life by redirecting our focus onto spirituality and the service of Hashem. This concept might also shed light on a different teaching in the Gemara – that whoever enjoys delights on Shabbat, "the desires of his hearts are granted to him." At first glance, this means that by enjoying fine foods and delicacies on Shabbat, one guarantees that all his wishes are fulfilled. We might, however, understand this passage differently. If we observe Shabbat properly, then "Notenin Lo Mish'alot Libo" – he is given new wishes, new desires. Proper observance of Shabbat gives us a new perspective, and resets our priorities. Thus, if during the week our primary aspirations were about wealth and material luxuries, on Shabbat our aspirations are spiritual. Shabbat refreshes our perspective such that our primary goals are a greater connection with Hashem, more Torah knowledge, more Misvot, more religious engagement. The ultimate purpose of Shabbat is not the cessation of work itself – but rather the renewed perspective that this brings, which leads us to reset our priorities and redirect our focus onto that which really matters.
