Parashat Vayakhel: The limits of creation
This week's parashah opens with an odd juxtaposition. Just before explaining to the Israelites how the Mishkan is to be constructed, Moshe pauses to exhort the people to sanctify the Shabbat. Why is the commandment of the Shabbat inserted here? The usual answer is that building the Mishkan—as important as it is—nevertheless does not over-ride the prohibition of work on Shabbat. But this only puts off the question: why are we are told to sanctify the Shabbat by ceasing all creative work on that day?
