hen we look closely at the details of the Mishkan’s construction, we notice an interesting fact. Moshe came to the people and gave them all of the details of the plans for the Mishkan. He explained to them the measurements and the materials from which it was to be built, as well as the construction of the items that were to go inside of it. Even with just a surface reading, it is clear to see that it would require professional workmen in order to build the Mishkan to HaShem’s specifications. Where did Moshe expect to find such professionals in the desert? The Jews were fresh out of Egypt, where they had spent the past 200 odd years working as physical laborers. They spent those years suffering, not learning the professions that the Mishkan required.
