שמות, פרק ל״ו, פסוק י״ט

Constructing the upper layers of the Tabernacle ensured complete protection and shelter for the entire structure. To achieve this, a dedicated protective sheet was crafted to function as an independent tent in its own right [אבן עזרא]. This covering, made from ram skins dyed red, was draped directly over the inner tent of goat hair.

An additional layer of tachash skins was then placed on top, though there are different perspectives on how these final materials were arranged. One approach suggests that the dyed ram skins and the tachash skins formed two entirely separate layers stacked one over the other, giving the Tabernacle a total of four protective covers. Alternatively, these materials might have been combined into a single upper cover, consisting partly of ram skins and partly of tachash skins. According to this understanding, the Tabernacle was sheltered by only three layers in total [ביאור שטיינזלץ].
