Musar su Levitico 23:32

When we look at the Sabbath from this vantage point, we can understand the phrase ששת ימים תעשה מלאכה וביום השביעי יהיה לכם קודש שבת שבתון. If the meaning of this verse had been that the seventh day should serve as Sabbath, the Torah should have written: ששת ימים תעשה מלאכה ויום השביעי וגו', "Six days work shall be performed and the seventh day shall be holy, etc.," instead of "and on the seventh day, etc." As it is the Torah wishes to tell us that "on the seventh day everything, including unfinished tasks from the sixth day should be considered as completed." The repetition of the words שבת שבתון together with the emphasis on the word יום also suggests that even if work is being performed the holy character of the Sabbath day itself does not cease. It is clear that this occurred immediately after the Day of Atonement, which is also known as שבת שבתון (Leviticus 23,32). The element of קדושה on the Sabbath comes from above יהיה לכם קודש (35,2), i.e. you receive the נשמה יתירה.
