Aliya Summary: When G-d commanded Moshe about the Mishkan, He first commanded the making of the Aron, Shulchan, and Menora. Then, the roofing layers – the Mishkan, the Ohel, and the Orot. Only then were the wall boards and foundation sockets brought into the picture. In the carrying out of the commands, a more “practical” plan was followed. The structure and then the furnishings. But how can Moshe and Bezalel deviate from the commands of G-d? You can’t just do whatever you want in this kind of thing.
Commentaries say that Moshe and Bezalel requested and received permission from G-d to take the more human, practical approach. In this Aliya, the three layers of ceiling are presented. Note that the first layer was a beautiful, multicolored weave and the fasteners were gold. Over that came the more practical, less attractive, less complicated, weather-resistant Ohel of goat hair. This layer was not seen from inside the Mishkan, and might not have been seen from the outside either, according to the opinion that the Tachash and Red-dyed sheep skin covering (which was also attractive) was not just on top.
