Tafsiran Bilangan 4:25: Rashi, Tur HaArokh, Rabbeinu Bahya & Siftei Chakhamim

את יריעת המשכן THE CURTAINS OF THE TABERNACLE — the ten lower ones,

ומכסה התחש אשר עליו, “and the covering of Tachash hide which was over it, etc.” Ibn Ezra writes that the verse abbreviated the description, omitting reference to the covering consisting of the ram’s hides dyed red, which also covered the Tabernacle. (Compare Exodus 36,19) Some commentators believe that both of these coverings were glued to one another so that they formed one cover.

ומכסה התחש אשר עליו, “and the covering of tachash-hide which was above it.” The reason the Torah does not mention here the second type of skin-coverings of the Tabernacle, the ones of red-dyed ram skins, is because they were attached to the tachash-skins. Alternatively, the reason is that the Torah omitted same in the interest of brevity.

ואת אהל מועד AND THE TENT OF MEETING i.e. the curtains of goats’ skins which were made as a tent above it (the Tabernacle).

מכסהו ITS COVERING — the rams’ skins dyed red.

מסך פתח THE SCREEN FOR THE ENTRANCE — the Veil at the east side.
