This posuk translated according to the vowel points under the word “vag,” is defined in the following manner: “Six days work shall be performed”, thus the emphasis is on the work which is performed. This is in contrast to the vowel points being read as “vag,” which would translate as “six days “you” should perform work.” Rabbi Shlomo Ganzfried Zt”l explains that only one who truly believes that his sustenance is from Hashem, and that the amount of work which he performs will not influence his livelihood, can rest peacefully on Shabbos. This is in contradinction to one who feels that his livelihood is a result of his effort and toil. Such an individual senses that Shabbos curtails his opportunity for greater financial security. He cannot rest his mind because he is uncertain as to what opportunities for financial gain he is forfeiting. To him the Torah admonishes “Six days work shall be performed.” Do not think that it is you that performs the work – it is to be considered as if the work is performed by itself. And the fruits of this labor is Hashem’s blessing. Only then will one properly fulfill “And on the seventh day shall be unto you a sanctuary: A Sabbath of Sabbaths celebrated unto Hashem.”
